[Fot] TR3 front end conversion to TR6 parts: Camber - moving the ball joint inward

[Bill]

Actually the late TR4 trunnions with caster seem to be more easily available and they have the pressed in shaft. At least that used to be the case as I recall. I have those trunnions in Peyote.

You will also need to retrofit the inner lower control arm bushings from the later model onto the TR3 mounting points. Everything will bolt together.

I will use “the” Jag ball joint and shim it as required.  Due to the complexity of shortening the upper A-arm or moving the inner pivot point inward, I am considering welding an extension to the upper A-Arm ball joint mounting tabs on the inside to mount the ball joint further inward and produce a similar result to shortening the A-arm.  I have not removed my TR3 A-Arms yet, but it appears there is room to move the ball joint inward at least an inch in this way.  I know I can’t go as far as those of you who have shortened the upper arms, but it seems like it could be a decent compromise.  I am concerned though, as this seems too easy.  None of you guys have done it. Instead you have shortening the upper arms which, from what I have read, is challenging, as is moving the inner pivot point and retaining substantial structure.
