You'll need an IRS to mount the transfer case at the back, but that's not a big problem. Instead of having so many u-joints for a minimum of room saved, angle the driveshaft from the t-case to where it needs to come from under the floor. Then put in a carrier bearing and another u-joint to swing it where it needs to go.

As for a hot rod instead of under another car, there's an easier way that looks feasible. Take a look at C-boy's project page. He has a "rat rod" with a Ford truck Twin-I Beam front suspension. Using a frame similar to that with a live axle in front, with the radiator in front of the axle (like C-boy's, only really have the radiator in front!), there wouldn't be many problems. Use a passenger side transfer case to solve some clearance issues, and use a straight six or four for more room. Most have nothing but the fuel pump hanging out the right side, and that can be replaced iwth an electric if it's in the way -- no exhaust or steering over there!

Use parallel leaf springs like an American Undersprung or use coil overs and hairpins/four links. Keeping the transfer case on the driver's side is doable, just have a raised floor. Driver would be sitting nearly straight legged on the floor though. To keep movement under the floor to a minimum having a two piece shaft going to the front with a u-joint at the bottom of the firewall/front of floor would work well. Get a Jeep Cherokee with 4.0L EFI six and you'd have all the parts needed!

I have to admit, passenger side transfer case would be a LOT easier. Not because of room under the floor, but because the exhaust and steering gear is on the left side too. CJs used a passenger side front shaft transfer case (through 86) -- it's even gear driven! Drawback: it's full cast iron -- a little heavy but bullet proof. Early full size Jeeps used passenger side transfer cases, later ones don't (not sure which years). A straight six FSJ would provide most of the needed parts or a CJ. The six lug wheels would be an issue though. Toyota pickups have a passenger side T-case, so one of those would be a good base for a light weight roadster. Forget using the frame -- a custom frame Z'd on both ends is needed.
