I have a 41 passenger car, but have a question for you 49-54 guys.

Im having a problem getting new upper link pins that fit, and I have 1/2 a theory as to why. Below is copy of a post I put in the 37-48 forum.

... The bushing wont even start to thread into the upper A arm.
(The old bushing hand screws in with no problem.)

I had a machinest look at the old and new bushings.
Old bushing: .979-OD .957-root thread diameter.
New bushing: .985-OD .964-root thread diameter.

I haven't called chevs of the 40's yet.

Does anyone have a 49-54 bushing that they can measure the OD and root thread diameter on.

I have this idea for two reasons:
This is the same issue I had with the ones from ebay.
(So maybe an entire batch got screwed up at the factory)

If I believe the pictures in the chevs of the 40's catalog, the bushings (and seals) look like they are from a 49-54 pin.
