Just bought my first B-body Olds.A 1966 delta 88 2 door. Its exactly like the one my family had new.Its not in bad shape except for a weak trunk pan from years of a leaking back glass.Has anyone tried to install the repo 66 Impala pans or is this something Im going to have to make from scratch.Thanks

 

While I suspect that they are not an exact match, the Impala pans look like they are close. Likely an easier task than starting from scratch. I've been comparing them to the pan in my 67 Delta for the same reason. I've found a surprising amount of commonality between the Delta and Imp for interior parts - package shelf, arm rests, glass, bucket seat mounting brackets and tracks as examples. Obviously the frame and suspension are completely different.
