Mike, probably could be straightened - the paint flaked off from the lugs through the bends.
While everything could be straightened, the paint was really the only special thing about the TI 20-30 frame - the power blue panels - and what was there was not aging gracefully any more.
It was all original with touch-ups, and I replaced the decals with my own scheme
So if I had to start over with this frame, straighten it, then repaint/decal, etc - the value of the frame is not worth the effort or cost.
I had rebuilt my old Grand Prix 3 times, first in 1978. The parts it was carrying many would call a silk purse.
Many times I had though about upgrading the frame. This wreck sealed it.
It made more sense to upgrade the frame than repair the wrecked frame - just wasn't worth the effort.
I'll still always be fond of it.
