Pretty sure it is...friend of mine has the cutouts w/ a 3" BL & he's runnin 33's w/ some minor rubbing. I had a p/u back in the day w/ 3" BL & 3" SL w/ the bushwackers & I squeezed 35's w/ minor rubbing.
this is true. but big tires are cool. LOL! just wondering if it will fit. my nephew has the 83. he wants bigger tires with out having to lift it. i'm trying to talk him into a v8 swap. mine is a 94 with the vortec and i really like it.
