I have a small lathe, but I can't see how you could compete with the cost of the molded one even if they are not as good.

Daves buddy could probably shoot them out like popcorn using a screw machine. Lathe work would be tedious. Worth doing for yourself, if you have time, not for others. I think Dave Kostich, also in Southern California, makes these as well. (not that material, but I don't know) He also may not sell to end users, I don't that either.

With your issue you need to remove the bolt and highly polish the bolt removing about .001"+. You can use a file if you wan, it accomplishes the same thing. Then the next thing you need to do is run a 9/16" drill bit through the nylon. The bit will want to grab so you need to hold the bit away as it will want to pull through.
Grease the bolt as you install it and it should slide right in with light pressure. There should be about a 1/16" between the nylon and the pitman arm, any more and it will have up and down movement possibly causing steering issues and at the same time The pitman arm should not have any metal to metal contact with the relay rod.

Maybe racingguy2 could knock out 100 or so on his CNC

Ya the screw machine was the bomb! What we found out is if your freeze the material before sticking the stock in the machine it would machine them nice and smooth, I used to buy the material in 10ft sticks! the screw machine would make 100 of them in about 1/2 hour.

I know an expert machinist if Dave would send me one to copy I'd make sure he got it back plus! Or even a print to go by.

My name is Mike Worrell living in southern Iowa my vairs are a 64 2dr convertible monza 900 with 110 motor 4 speed light yellow with blk interior. Then a few months ago I got a 65 2 Dr convertible monza 900 with 110 motor 4 speed
Also light yellow with blk interior. Not sure what gear ratio as of now I'll have a look and up date. I really like them both but really liking the 65. They really made a lot of changes in a 1 year difference ????

I've used a brake hone to enlarge the hole in the nylon bushing.

I worked NCR all my working life. If you took all the lathes, mills and screw making machines in the Dayton factory and put them end to end, it could be miles. I can see how a screw making machine could turn these out like cord wood. Also, over the years many brass, bronze and other materials were replaced with delrin type material, that is some tough long lasting stuff.

I just put one of the Clarks nylon ones together this afternoon. No way the bolt would fit. I ended up reaming the nylon after it was pressed in with a 9/16 reamer and then it pressed together nicely.

Right!
And using a 9/16" ream or drill will give .002 clearance on the bushing.

I remember a while back the ORIGINAL maker of the nylon bushings offered to make more or maybe even supply dimensions for new ones to be made. I probably have 30-40 of the original run, from maybe around 2000?, That dimensions could be taken from.

As we all know the copy of the copy has some flaws like being to short many times and also with to thick of a hat section.
And then there are the complete units, I have one, the bolt is way to tight even uninstalled.

Thanks Ken. The hat on mine is definitely too thick. That may be why I have to over tighten the nut to get to the cotter pin hole. I'll try reducing that thickness and see if the bolt to the pitman arm fits better and doesn't bind. I'll also contact Clarks. This seems like an ongoing issue with the part.

This is a good idea. If I run across another tight one I may try this technique instead of my sandpaper drumsmiling smiley
