Frame X-member diffrences: Convertible vs. Retractable

[eberhama]

Thought I start another round of stump the experts. Anyone know if the x-member in a '57 retractible frame is the same a the one in a convertible? I know the frames themselves are diffrent, I'm just concerned about the X part. TIA, Matt

The 51A has longer 1/4 panels, but I believe the wheelbase is the same as a 76B . If the wheelbase is the same the "X" would be the same.
