What is the correct spacing for a '26 coupe?

I bought a steel frame but I'm not even sure that it is correct for a '26 coupe.
Also bought an aluminum one. At least one of these is wrong.
Aluminum frame has a 1/2" measure, steel has 7/8"

Vern, I'd go with the one with the closest measurement since your rusty steel frame is unusable.

Terry, I agree, unusable but...
maybe the aluminum one also is unusable if it shifts the frame up 3/8". That leaves
1) a gap at the bottom above the cowl and
2) the bracket on the windshield frame (circled in green) no longer lines up with the bracket on the A-pillar for the slider to operate correctly.

So, what is the correct spacing for a '26 coupe?

Would a 3/8” shim placed on top of the aluminum hinge put the geometry correct? It looks like it might be invisible as the curl of the hinge is taller than the steel.

Tom - genius idea. Yes the "curl" is above the header, in either position.
I would just need longer screws to go though the extra material.


Actually, the hinge is not deep enough to even reach the screw holes in the header, none of them. Aluminum piece is flush against the header face. It should have never have had that 3/8" step. I do not have TIG weld skills nor equipment to add more material and need to think more on this one.
