I see you got a lot more response over at the HAMB, so I guess I'll bump this and offer a few points.
Make darn sure you check all the rod parts companies. Order up catalogs, check websites and ask for prior experience (like here). It really stinks to find out AFTER you've done something that there was a good easy way already figured out.
When doing any swap, figure out what's required and what's flexible. Small notching of sheetmetal and frame is okay, the steering and exhaust can both be moved, but the best is to find stuff that works together, can be serviced easily, and is commonly available. Don't build until ALL components are thought out and planned for. If you want power steering and brakes, A/C and cruise, make sure you know all the options available, and pick the best fit and price. Then see if each works with the others. The hard part isn't the build, it's the design before hand.
