Sorry to hear about your troubles! I too have the .5" lower body mounts and redid the tunnel top on a rust free floor...not what I had planned but the T56 had to fit and I had already welded the SFC's in at that height. Kyle offered to swap out my mounts for stock height but I decided I would rather do the tunnel than revisit the SFC's. In hind sight I probably should have swapped to stock height mounts to make many other things work easier...live and learn!!
Good to see you are back to making progress!!
