guilty as charged...
just to clear a few things up.
there is no such thing as a true black LS1 seat (at least in leather). It is very dark graphite grey (like the ones in my car).
The LS1 power seat tracks do not directly bolt in...you'd have to do some modification to the car OR build some adapter brackets...they are close, just close enough to make adapting them a majot PITA. If you want power seats, find some G-body power seat tracks and bolt them up.
The air bolster adjustment is easily hooked up...power and ground. The pain here is the air compressor for both seats is mounted in the seat base of the passenger seat. SO, you have to run a bunch of wires (4 or 6) AND some air lines from the passenger side to the drivers side. Not hard, just a bit of a pain (gotta pull the console, seat belts and get the carpet up).
The G-body seat tracks bolt directly on to the LS1 seats...I put 1/4" spacers on the front track mouting point (to the seat) because the seat needed a little more rake IMO.
By the way, once you convert you will truely realize how CRAPPY the OEM Regal seats are...it's the best mod I've done.
