The left side is with the subframe bolts tightened down all the way. Right side the is about 1/4" between body bushing & floor.

Scott, here's a thought. Maybe your floor pan may have sagged over the years, if it's an original floor. My firebird has original floor pan, and the original crossmember will hit the floor on the pass side. A floor jack with a 2x4 underneath the sag fixed that.
