Quarter Panel Replacement Question

[mrr1999]

Hey guys-

I need to replace a QP on my Camaro and I had a question. After stripping the car down to bare metal, I notice that the lead seam on the sail panel is not there. Its one solid piece going into the roof. I know the previous owner had it replaced once in the 70's , but that was grafted in at the body line down by the door.

My question is, since the replacement panel is beveled at the top where it mates with the roof, and the current panel doesn't have a seam, will I have a problem joining them together? Without the lead seam, the roof doesn't have a matching bevel for the new QP to mate with.

Thoughts? Thanks!
