Pitman arm and gearbox issue

2108 Views 40 Replies 12 Participants Last post by  CHOCK
I have a 1967 mustang v8 manual steering car. My dad bought it new in 1966 so it is an early model. I needed to replace my steering components since they were pretty worn out.

I bought a Lares 18702 which has a 1" sector shaft which is what my car had from the factory as my tag was smb-a. I bought a 1 inch sector shaft pitman arm using part number c7za-3590-a which according to stangersite that should be my part number.

Now my issue is that I cannot get the pitman arm to go over the sector shaft by more than maybe 20%. Did I miss something in my parts ordering? Has anyone else ran into something like this?

My thought is since it’s an aftermarket box, there could be bad machining of the threads on the shaft or a mis-boxed nut that could cause issue with tightening.
Yes indeed. These things are possible on anything made by a human, any machine programed/controlled/operated by a human. Stuff happens for sure.
I think we are at 50+ of the same boxes sold we get out of China. Same issue-Nuts are too thick, pitman fit great (has to have the torque) to press the pitman down on the new splines.
