The forward edge of the cross tube proved to be exactly in line with the rear edge of the second pair of body mounting holes (arrow), the first pair being at the cowl. The cross tube will slide forward and wedge into place at this location. However, I elected to move the cross tube, and thus the whole Super X, rearward by 1 1/2 inches in order to align the rearmost weld of the crossmember side 'rails with the kick-up of the chassis. This was for appearance, the fact that I'll likely mount the body further back than a stock Model A to gain some extra engine compartment room, and to gain a little extra clearance for the transmission. As I probably won't use the brake master cylinder bracket (ground clearance would be an issue with the Z'd frame) this won't be a problem, though the cross tube now had a slight gap at each end.
