Is there some chance of getting a better picture of the texture of an original firewall pad? There are some good images posted on other threads, but they don't really emphasize the texture nor the dots ... its hard to tell if the dots are "pressed into" the surface, or if they're part of the plastic itself.
I did not see a reply to your request. Here is a 67 SJ pad with dots, suspect that the basic patter stayed the same - someone will chime in for sure if I'm off.
