68 Firebird Convertible Minitub issue - Need Input on fit issue

[digitalman2112]

Issue: The convertible top body mounts (where the male hinge bracket and the b-pillar support brace mount) are located in a place that prevents the new tubs from being mounted.

Here's the body mount that is in the way (same problem on both sides)

Attachment 159886




I welded in braces to hold the brackets in their original positions. From my initial attempts to fit the tub on the passenger side, there is as much as a 1/2 inch of movement needed, even with the outer portion of that bracket that contacts the tub bent flat.

As I see it the options are:
1) Move the brackets which changes the positioning of the convertible top, but is possibly adjustable (The fabric top is already on the frame and I'd like to ensure that I can reinstall it and have it fit)
2) Mod the bracket to remove material to keep the tub intact (I don't know that these brackets can be replaced easily, so Im hesitant to mod them)
3) Mod the tub to clear the bracket (probably the easiest option)

Those that have mini-tubbed convertibles - did you have this same issue, and how did you resolve it?
