64 Impala SS convertible rocker panel question
I'm new to the site and looking for information on rocker panel replacement on my convertible. I have searched the threads and found lot's of information but can't seem to find an answer to the problem I'm having. The inner panel is in good shape. I have purchased the outer panel with internal supports and also the heavy u shaped support braces that weld to the bottom outside of the outer rocker panel. There is also a heavy internal support brace extending from the front of the rear wheel house ( the lower B pillar welds to this piece) to about halfway through the outer rocker panel. I cannot find this piece anywhere. Here is a pictured of the piece I am talking about.
Does anyone know where to find this piece or do I have to fabricate something? The internal support with the outer rocker panel that you can buy anywhere on the net is not the same as this support piece. I assume this is extra support used on convertibles only. Any help would be appreciated
