You modified a hard top birdcage into a convertible? Interesting...

Sort of...
The base bird cage - vert or t top is the same. GM spot welded on the T bar and roll hoop right into the upper b pillars.
All one has to do is use a nice sharp spot weld drill and pop those out, then the roll bar and t bar lift out. I had the convertible cage, so I drilled out the spot welds and slid the convertible top nut plate and transferred it over. I've done this a few times now - usually easier to find donor T top bird cages than verts. In fact, I have a 1975 cage stripped and sitting by my shop that I have to do something with ASAP.
Once the parts are moved over, reassembly isn't that bad. Just takes time to get everything prepared, clean...and ready to bond and rivet.
I used a Lord Fusor product and feel really good about added rigidity in this structure thanks to better adhesion technology. Now, one thing I did do a bit radical is I kept the 1978 STEEL floor and ditched the fiberglass floor. I feel way better about this for being more rigid and better support for seat mounts, seat belts...etc. It is clearly NOT a numbers matching machine!
