Thought I would share with the group that I finally "cut to the chase" and had my local welder cut out 6 inches from my ROPS. I re-installed it today and it is 79 inches high, which clears my garage door just fine with about an inch or two to spare. I was concerned about the garage door motor, but it cleared it just fine. It had been off the tractor since last fall and I wanted to have it on the tractor, but still be able to get it into the garage.
In spite of their best efforts to keep it straight, it was off by just a little bit and it took some finagling to get it re-installed. So if any of you with welders decide to tackle this, be careful when lining it up for welding after the cut. There is not much room for a "mis-adjustmnt". The cut will need to be made closest to the joint.
I also installed the recall kit for the spring clips. It is just a retainer ring to make the cable longer, although they do include new spring clips.
