1200 front stud part # 40222-22100

1200 rear stud part # 40222-18000

 

Cannot find my S130 catalog ATM....anybody with a catalog out there that can answer the ZX stud question?

 

Edit ...several hours later.

So it would seem that I no longer have an S130 catalog......dammit.

I'm going to check out some Civic seats today. I hope they are half as nice as the owner says they are. I'm hoping that they are not too big or tall for the car. I was thinking of getting the original seats reupholstered, but I'm not going to be able to afford what they are going to want for the job. I've got too many projects going on and I'm by no means a wealthy man.

 

I'll try to get some work tomorrow and post more pics of the progress.

 

 

FWIW, 240Z seats are a pretty good fit, and aren't too hard to adapt to the stock rails. And fairly cheap to reupholster...

It's your car, just don't ruin it.

FTG, Make sure and use a thread checker on those larger than life front studs. Sometimes folks replace the OEM 12.5mm x 1.25 studs with aftermarket 1/2" SAE fine thread studs. The threads look quite similar, and they will even allow you to start threading a metric nut onto the SAE stud...until it cross threads and buggers up the threads. (this is an "ask me how I know" topic, btw)  Also, if you go back to OEM studs, they may not fit the hub as snugly as they are supposed to due to the aftermarket studs having a slightly larger shank and reaming out the hub hole a bit oversize. ARP makes some darn sexy racing studs that are 12.5mm x 1.25 (for a Subaru) that have a nice tapered end and they may fit the oversized hub hole that the 1/2" studs left. (I'd post a picture, but I have only a few years left to live and can't waste my time trying to fumble through the pic posting procedure here. :-)  ) Cheers,

DF already confirmed that they do fit. Thanks for taking the time to check.

Those seats look real good in there. There's a guy locally that has tons of datsun parts. I'm going to check with him to see if he has a good set.

I confirmed that they were 12mm x 1.25. The studs went in nice and tight when I hammered them in.

I have the front struts almost finished. I put new rotors, brake lines and pads. The old rotors were worn down but it appeared that the bearings had ben changed not too long ago so I reused them. I also realized that I did not take a pic of the caliper on the strut. I'll do that tomorrow with further progress.

The difference in length of the studs. The shorter one is the front zx, the middle size is the one the 1200 came with and the longer one isthe ones you get from napa auto parts.

A few questions: what's the torque specs for the inner and outer tie rods and the ball joints? The inner rods are stock 1200. The outer tie rods and ball joints are from an '80 210.

What about the springs? I've read that if I cut the springs a coil the spring will get stiffer. How are you guys doing it? How many coils are yiu cutting? I will be using collar clamp to set the height.

How much should i take off of the spring perch? Obviously enough for the strut to go through. Here's a pic of how I've cut them so far. Which is best? I have a welder so I can fix them if I've messed it up.

FYI you can get new upholstery from MSA for less than $300 a pair, and they are pretty good quality. Not too tough to install either. So if you find some rough ones, you can recover them and have like new seats on the cheap. 

 

A few questions: what's the torque specs for the inner and outer tie rods and the ball joints?

 

I don't think they really have a torque spec? If you're using the cotter pins, just get them as tight as you can with a ratchet and you'll be fine. 

 

 

 

How much should i take off of the spring perch? Obviously enough for the strut to go through. Here's a pic of how I've cut them so far. Which is best? I have a welder so I can fix them if I've messed it up.

 

Assume you're cutting the 1200 perch to fit inside the 280ZX perch? If so, you're fine. 

 

As long as you have at least an inch or so all the way around it will hold the spring. You can cut it down to just a giant donut, or leave it as is. You don't have to weld it in, but it is nice piece of mind.

 

Another way we've done it is to find a piece of pipe with an ID just bigger than the spring, cut a 1" tall slice out of it, and weld that in.

Thanks for the tips, DF. I'll call the guy tomorrow about the seats. I'll also torque the steering tomorrow.

So the spring perch on the right had enough meat? I'm going to use collar clamps to adjust the height.

Can I cut the springs about a coil and a half to firm up the suspension a bit? Any problems with that? Going to use some old tokico shocks I have laying around.

I have the struts ready to go. Should I use 1" bump steer spacers? I have a couple of sets.

All the steering linkage components have factory torque specifications.   I  can look them up in my manual when I get home.

 

As far as cutting the springs...I would not recommend this.   On my 1200 the previous owner did this and it ruined the suspension.  Yes the car looks awesome but it sucks in reality.

 

I bought KDFL model King Springs to replace them which have a lower right hide but maintain a good spring rate.

Thanks njoz1200ute. I found the torque specs on an online factory manual.

I'll look for those springs and other brands, as well.

Sorry, misread. Not enough meat for collars. I thought you were nesting them in the 280ZX perches. My bad. 

 

 

Can I cut the springs about a coil and a half to firm up the suspension a bit? Any problems with that? Going to use some old tokico shocks I have laying around.

 

I have no issues with cutting them. Done correctly, it's never been a problem for me. 

 

But honestly, you've gone this far. Wouldn't threaded collars and 2.5" be the way to go? Then you can have any rate/height you want.

 

 

I have the struts ready to go. Should I use 1" bump steer spacers? I have a couple of sets.

 

I wouldn't. Wait until you see if it has a bumpsteer problem, but that's me. Also, with the spacers in, your wheels might not fit any more.

You're right. I didn't want to go with the treaded collars but I think I'm going to do it. I'm even going to go with camber plates. I have that on my other 510s and I'm quite pleased with them. It's just that much easier to get the ride height you want. What spring rate should I get for a street car? I was thinking 150lbs? Like I said, I'm new to 1200s. I don't want a harsh ride but I want it to handle well. Roads here in Cali are not the best.

Here's what I've done today. I'll have to continue on Sunday.

I test fit the wheels and they fit without clearance issues as far as the rim hitting the control arm or any other suspension component.

150 is a good start (with an A-series). I'm on 200s right now and even without driving it I can tell you it is STIFF. Probably going to step down to 175s soon. 

 

These cars (and engines) are a lot lighter than a 510, so you definitely want softer springs in the front than you'd run on a 510.  :thumbup:

Awesome DF. Thanks for the reassurance. I'm going to go ahead and order them tomorrow. I'm tired of working on this car without being able to enjoy driving it. After front suspension it will be bleeding the brakes then off to get an alighnment.

Nothing exciting this week. Installed new rear shocks, brake m/c, bled the brakes, ordered new camber plates and front coilovers. Here are the boring pics...

Not sure. I haven't looked up the part number. They came with the car along with other miscellaneous parts. They bolted right up and appear to be about the same length as the old shocks.

 

I got the coilovers and camber plates in yesterday. I'll start work on that on Sunday. Also have some sound deadening coming in monday. Once I cut the rusted piece of floor behind the passenger seat, I'll start applying it and put some carpet. I want this car as quiet as possible.
