Well after close inspection and trying to pull things straight I'm going forward with the the cab swap. Drivers side A,B,C posts are all twisted. fire wall has a slight bow in it.Just about every structural member has a problem in the cab area.
looks like most all parts are universal as GM did for so many years.As soon as I get to the point of pulling the cab Ill start taking pictures to post.
Wish me luck I'm going in!!!
