Welcome to BC from another Phoenician
Sounds like a very ambitious project
I know my '97 (as well as '98 and '99) has a stock vertical PCM holder and cover, but I don't think the 2000+ PCM will fit in the holder. '96 came with a holder with a lid that leaves most of the PCM open for airfolw I assuem, but again, I don't know if the 2000+ PCM fits in the holder. If you want to try to see if your PCM will fit in my '97'* PCM holder, it, I have no problem stopping by and letting you test fit it. Also, Intense-racing.com sells a PCM tray that allows you to relocate your PCM.
