Mine is a 3 degree caster car.
They gave me a printout showing the left caster at 3.0, while the right is
0.8. I had replaced both trunnions with TRF sourced units. I will have
another look to see if anything is obvious.

How much is it out? Which direction? Any chance the upper A-arms are not
assembled properly? For the early type (0 caster) arms, the front arm on
the right overlaps the rear arm; but on the left side it's the rear arm that
overlaps.
You can probably get a fraction of a degree change by moving the upper pivot
on its bolts. Beyond that, it's either replace the distorted piece, or bend
the frame, or install custom pieces.
ISTR it was Herman van den Akker that reported finding a bunch of distorted
vertical links; which I think might show up as incorrect caster (and/or
camber). The upper A-arms can also sometimes crack such that it's not
immediately obvious.
Also, as I'm sure you know, 62 was the crossover year for the trunnions. If
someone accidentally installed the wrong trunnion (which would take a fair
amount of force I suspect), that might show up as incorrect caster as well.
