Back to life after crash in 2011 problem 1972 C-20

[terry b]

After a crash in 2011 the truck is back together. Replaced radiator core support hood passenger fender and inner fender. Had some frame work. The problem is when I shift the truck 402 with a turbo 400. The shift lever moves with no detens until about half the travel is used up. Checked linkage no damage to the column or the rod. But the mounting point on the transmission is bent but intact. Shifted fine at first with a little slop but now it will not lock in to park and detents don't line up marks on indicator. Could I have broke something inside the Transmission?
