BossHawg,
Are you wanting to put tires in that fill the fenders, what's your ride height, are you planning on tubbing the bed?
These questions all need to be answered so that you get the look you want. You can use a 2WD S-10 rear if you want to run 10" wheels with lots of reverse and tub the box.
If the front is already Corvette, you should do your best to match your track width to the front, don't worry about what the truck was originally. In doing this you have to take into consideration the wheels you will be running and their offset as well.
