OK, so now I have the machine running right, time to start on the interior. i have a carpet kit from 914 rubber, so I'm good there - but the firewall monstrosity - I thought 914 or someone else was making a plastic replacement, I seem to recall the 2 sides separate, and they would rivet to the middle plastic piece?

I looked on 914's website, and do not see such a piece,

am I hallucinating / creating false memories? or does this piece really exist. I dont want to try and make that warped stained cardboard POS fit in and do the job.

It's called a back pad

Thanks Chris, I just ordered it up! i couldn't find it in the internal panels section, but when I searched thermoform, it came right up - thanks Makenzie!
