Lenie --
These are wheels (Budniks) for my buddies 55 2 door Post (Chevy). It has an Art Morrison chassis and an LS2 and Tremec 6 speed... he has Chromed out Tillers all around - the problem came when I finally stuck some front sheet metal on and discovered he had ordered the fronts with the wrong backspacing. So had to order a correct pair. The fronts he mis-ordered would be the CORRECT for that size on the REAR. He just picked up the wrong column.
The rears are 10" 18's - the fronts are 8" 18's
