Are you on Facebook? Someone asked this yesterday there. :D
I know you aren't asking me, but I will toss in my thoughts anyways.
I used the OEM stuff for my CC swap. Mostly F-Body stuff, but (I think) most of the parts are generic beyond the actual mount for the under the hood part. Biggest trick for me was wiring in a switch that killed the CC on my clutch pedal. Works as well as it did stock, which means the initial set point is always low and needs a couple of pokes to the set button to get it where I want it. But after that works really well, very happy to have it.
No idea how accessible the OEM stuff is anymore, but when I was doing it I felt pretty lucky to find the brake switch that I needed. They seem to be out of production. But someone on FB suggested a NC relay and that would do the exact same thing.
