This is part number 720102. According to the manufacturer, it fits LS1 F-bodies and LS1/2 GTOs, and LS6 engines as well. I bought it, took it out of the box, and never installed it. It's aluminum, SFI rated, 7.25 pounds, 10% UD. Aside from some minor box damage, it's brand new. The lowest price I see for it online is $340; I'd like to get $275 shipped.
