Hi, Ive been gone a while and really forgot a lot of stuff. I have an 86 Cutlass Supreme it has the factory Chrome 442 type wheels on it. Im running 205/60/14's in the front, how big can I go in back. Id like it to be a Radial T/A size so I can match them front and back. The car has a 403 with a 2004r and factory 7.5 inch 2:49 rear. Turns out my 373 posi is seized and filled with water.
