Mike if you plan appropriately there isn't a lot of brackets and pulleys to switch. Personally I would leave the ones on your current motor and source from the vendors. I think with planning this can be pretty much a drop in.
IPSCO has crank and water pump pulleys, and new A/C bracket.
Alternator brackets are minimal and needs to be changed if you decide to change the style of alternator. Kirk Evan's from Amerisport would be an excellent source for you to contact and talk too, knowing your car. He will know exactly what your motor can do with the smog and without. He may even suggest his bulkhead reduction kit that includes an ac and alternator braket, plus increases room in your cab.
