Rear mini tub or Alternate.

Good day Gents. I'm inquiring on a mini tub set up or larger factory wheel houses for my 65 Valiant Sig.. I'm wanting to go pro/cruz/strip. In an effort to retain as much useablity and function of the car, I dont want to put in some giant *** race tubs. I'm looking for around 10-12 inches of tire on the ground. I'll narrow the rear as too the tub set up.I'm in the welding stage of my rebirthing of the Signet. I'm wondering about a possible late model or b/c-body cars. Any advice would be greatly appreciated.
