Patch panels.

Early A's are different and not available from Classic as far as I know. ABS is the only one I know of that has decent quality floor pans for the '66 and older A's. Even theirs need to be messaged a bit, but, they fit pretty good.

Right you are 63-65 B body. I didn't look close enough. Thanks for the correction. Always good to get the right info out there.
