We finally installed my C.I. Belhousing last Summer. I say we, A few of the Green Mountain Cobra guys & myself. Mine Being a 5 Bolt, rare & extremely overpriced, I found an ANSEN HRA Bellhousing. It must have originally come with a Spacer between the upper bellhousing & the lower inspection cover. That or the flywheels back then weren't as thick out near the ring gear. We had to do some grinding to get the inspection cover to clear. Once I got her home I built a makeshift spacer, about 1/8" thickness. The mounting surface(lower face of bellhousing) was angled so that a spacer shifted the cover forward, just enough. PITA but, at about 1/4 of the price, It worked out just fine & looks great sitting in there. I saw an original comp cobra, recently, that had an Aluminum bellhousing. Do I get points for this???!
