Thanks for the reply. It sounds like it may be easier if use a different donor than the 1990 C1500. Iíd like to minimize modifications if possible.
LOL, actually I think it was a very good donor, I would also look into the other options maybe the B-Body stuff, like I said some of my issues were self inflicted, and it was drivable day one, and always has been. And if you are considering a steering box swap (like the JGC one!!!) that is the time to do it, and save all the hassles with different fittings. Best part, it is all proven stock parts that last forever, work, and are cheap to obtain and maintain. And while they are not attractive by any means, I don't like pulley bling on an engine anyway.
I think I may even look into 1992ish B-Body setups, I think they had stamped steel main brackets, not cast aluminum ones, might look a bit more appropriate.
Just remember you are changing everything in front of the block and behind the fan shroud. Don't forget you need a reverse rotation water pump, and fan! Also they are all long pump setups, so make sure you have room for the fan and fan-clutch.
And when putting in an internally regulated alternator, it is super simple to wire. YOu use all existing wires in the car, just jumper bypass the external regulator, and make sure you have a pigtail for the alternator to tie into the existing alternator connectors.
