The shims you mentioned are for toe-in, they are between the swing-arm
brackets and the frame. I think the shop is correct here.
The camber is set by a combination of spring height and the design
of the swing-arm brackets themselves, as far as I know.
Have you recently installed new `competition grade' rear springs in
your '70, by any chance ??? All of those replacements seem to be
made to fit the later model cars, and now I can't remember when the
big change was, '72 or '74.5 maybe. I made the same mistake in a
TR-250 I had, and wound up with exactly the problem you describe;
I can guarantee you WON'T like the way your car corners, with the
rear camber obviously positive, as you describe !! It'll scare you
even if you're fearless !
Have you had the swingarm brackets off the car, to check for frame
soundness perhaps, and upon re-installation, reversed them, inner
for outer ? There are 3 different brackets, coded by notches,
I think style #3 was added at the `big change' date noted above
but still used one of the earlier two. You might do well to find
someone who has a known original or proper bracket set-up and also
spring height to go with it.
