I gotta jump in here I am new here but play on the HAMB. 
We just did my dad 52 Chevy Sedan Delivery with all late model corvette suspension. While it sounded cool, looks neat and has great brakes. It was miserable to use the whole cradle. We ended up putting the whole thing into the stock frame width but had to Z the frame to get it low enough(front and rear). It was a ton of work and looking back I do not think we would do it again.
We used March brackets to get the accessories up. They are much cheaper than Street and Performance or Billet Specialties(which I sell). These are very open brackets and not as bulky looking as the stock stuff however....
Use the vette bracket. This is a good economical fix. We just used one on a buddy's 'baker.
There is also a bracket that was on "non-smog" LT1 motors. I can not find the part number right now but know when Miles Cook was with Car Craft they listed that part number. I beleive it moves the stock compressor up slightly.
Hope it helps.
