You are looking for a set of GTA rims like These off Ebay, but you really need 4 "fronts" instead of of two fronts and two rears, which is a "set" pf GTA wheels.
The GTA rears will work on the front with 3/8" spacers and longer wheel studs, or will fit in front without spacers if you have 12" brakes. GTA rears will NOT fit in the rear of a T/R unless you have at least 1" wheel adapters.
