I agree, the camaro is desired for it's front sub frame but now days it's better to buy an independent front suspension kit that's been engineered specifically for this application. I've done a Nova clip on my 48 Fleetmaster and it took days worth of measuring, grinding and welding to meld the two. I can see where it could be VERY easy to mess up and ruin both pieces.
As for the other stuff, I've used Monte Carlo drivetrains along with the tilt column and powerseats and what-not,
Just my 2 cents worth,
