So I've seen numerous internets saying the S110 H190 is a direct bolt in to the B310. Just how 'direct' are we talking? Likely the E brake and brake lines aren't exact, what else? Oh snap brake bias will be all wrong too... Am i going to have to get a new driveshaft too (likely)? I know its slightly wider, which is fine, I just need to know the big rocks I'm going to have to move to bolt this thing in. Thanks in advance for your replies.

Get the e-brake cables and handle from the S110. Then it's basically plug and play. 

 

 

Oh snap brake bias will be all wrong too... 

 

Get the front struts too. And use a S110 master. Problem solved. 


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

 

It's also not my money, so i'll suggest the most expensive option.

Get the S110 crossmember for easy KA/L/LZ swapping.


If equipped with an L20B, less likely if it has the H190, grab the oil pan also.

The S110 only came with Z20E and the Z22E. It's the '82-'83 year you want for the H-190. I would love to have one.

Was it S10 then that came with the L20B and an H-165 diff?


I know there is a combo out there like that.

Either way, crossmember will bolt to 210 making KA swapping easier.

Just got back from picking it up from the junkyard. Unfortunately they pulled it and ditched the rest of the car a while ago so i literally only got the diff. They pulled it all apart and there's no bolts anywhere on it almost. Its gonna need some lovin before i can put it in. They cut the brake lines one caliper gone no rotors one cable cut...a standard junkyard hack job unfortunately. But its in good shape. Going to go measure the shaft flanges and compare.

Driveshaft flange is the same, which contradicts what I read on Datsun1200.com about h190 vs h150 flanges. The nose is about 1.5" longer though so I believe the shaft would have to be shortened but at that'd be it other than the ebrake cables.

You should never believe anything you read in that wiki, by the way.   :rofl:

I believe only the 1200 is a different bolt pattern on the flange.

I was very surprised that they use the same flange. Hopefully my H190 LSDs at home also use the same flange. If not should be able to swap the input flanges around with a new seal. The only challenge will be to find a replacement right side e brake cable as they cut it. Everything else is readily available.

Does anyone have a blow up of the rear axle and associated parts? It seems like something is most definitely missing between the axle tube and brake mount.

Thanks. So the junkyard had the axles unseated...couldnt figure out why the brake caliper bracket was sticking out so far, I thought maybe a spacer was missing until i just pulled the axle all the way out and saw that was impossible.

Good time to replace both inner & outer axle seals.
