1968-1972 Tempest, GTO, Lemans hard top frames are all the same. 1968-1972 convertibles are all the same to. A convertible frame will work in a hard top (just has a box section alone the rocker area. Don't use a hard top frame on a convertible car. The box section give the car more strength that the convertibles need.
ps. 1968-1972 Skylar, Chevelle, Cutlass frames can be used - Their all "A" bodies. Motor mount holes may or may not be the same??? I'm not possitive.
