Cregg, why don't you take the car into a good quality frame and
suspension shop and have them check it out on their equipment. I think
it will be a good investment in saving your sanity! You may find some of
the suspension mounting points tweaked. (I know the frame on my TR4 has
some interesting post-factory twists and turns.) Besides, the shop may
love to see a car that actually has a frame under it, unlike these
modern, robot welded, stamped/formed tin-can, unibody contraptions. They
may be able to straighten it, if needed, pretty easily too. I recently
found just such a shop, one that specializes in collectible cars and
even had books and magazines with TR's in them in the waiting room!
They'll be seeing more of me!
