So after some research it seems all tapered inserts are made for jeep wranglers. There are three common sizes with the stock tj being the smallest.

TJ Tie Rod End - bottom of stud (larger end of taper) = .62"

620 Tie Rod End - bottom of stud (larger end of taper) = .60"

 

The Goferits used in the ka24de build are too big and will allow no pivot in the TRE.

Bellow I will post instructions on how to modify teraflex inserts to fit like stock.

These are the inserts

53360d865ae5de7e14000af5_grande.jpg?v=14
 

As you can see there is a slit that allows for expansion.
 

In order to make these fit you must open that slit with a dremel and slowly pinch it together in a vice being careful not to distort the shape.

 

 

Below I will post a before picture:

As you can see the insert goes all the way up the TRE without seating properly.

this can also be seen in acehaole_620 Ka24de Forum:

Here is the after shot:

Here Is stock Fitment

The new outer Diameter of the insert is .7" from .75"

 

I am going to fastenal's to get a 45/64 drill bit to test these on a spare idler arm. Will update soon.

I can see why some guys were trimming off the head of the insert.

Thanks for this :thumbup: 

 

Looking forward to results.

Whenever I think that I'm out of my mind for putting this much time and money into an old Datsun, all I have to do is look some of your threads to know that I'm not nearly as whack as you are.

You're going to skin a few knuckles, stand up too fast and bump your head, hunt around the floor for the nuts and bolts you dropped, invent a few new cuss words and when you're finished you'll say "That wasn't so hard after all!"

Just so we are clear, this is an alternate way of modifying the centerlink rather than flipping it and re-machining the tapers? 

 

You drill the taper all the way through, flip it, then sleeve it with these inserts?

Yes that is correct, additionally the teraflex don't require welding.

The benefits of tapered inserts over tapering are cost and ease and strength (compared to a double taper). For reaming you should weld the other side shut (before re-tapering) rather than having a double taper. Reaming should also be done on a milling machine (possibly drill press) not by hand or by drill.

No probs, sorry I didn't get this up sooner for ya.

Drill bit should be here wednesday. will update then.

You could maybe shave the top of them a bit but it probably won't have as much play as stock still (Especially since the rod I was testing on didn't even have a rubber boot to clear).

That link seems to just take me to this page for some reason

This is what I got: https://www.summitra...arts/tmi-990175

Inner diameter isn't listed but the smallest outer diameter is .75"

 

Also fully tightened it went up slightly further than stock so I will be getting a 11/16 to try as they will probably be easier for most people to source too. Will update again when I get it.

Thanks, glad its helpful.

No probs.

Oops I was messing up some links last night while going back and for copy pasting. :lol:

It is the same part number that I was looking at, cheaper on summit. :cool:

Sorry if I wasn't specific; i'm trying a small drill bit not a different insert. 

Original test was .703mm(45/64) new one will be .682 mm(11/16")

from my research there aren't any smaller insert to try.

If you find inserts ment for anything but a jeep or chevy 1 ton let me know and i'll check em out.

I would still machine the tip of the insert so that it sits below the surface of the forging. If you were careful, you could knock it down on a belt sander.

A washer between the nut and forging would also be a good idea.

That depends on the height of the cotter pin hole. If a washer will make it impossible for a cotter pin to be installed, then you shouldn't use a washer. And vice-versa.

11/16 hole had better fitment. ill post pic when i install on truck an you can see. The movement should not be reduced by the lip on the insert.

 

Edit: I miss read the first time, I will sand down insert if needed to clear cotter pin.

Wouldn't you want to take it down so that the insert couldn't possibly shift the amount it's sticking out on the nut side?

Probably wouldn't be a bad idea. Realistically I don't see it happening due to the pressure but ya never know. I probably will now that you mention it, just for peace of mind.
