Did mine about 6 months ago. Completely removed the Al ring. Cleaned the ring, glass and both sides of canvas with razor blades. Was a lot of work! Coated all with the 3M primer. Glued together with the 3m urathane. It was messy and took 2 people to assemble. I had bought the supplies when it first started failing, needed to get all new stuff when I did it, it has a short shelf life. Between the two batches of stuff $160 ea and the time to clean everything, probably 16 hrs. And re assembly, one day for the ring glue up, and a second day for the window glue up. About a month after getting that done the tension straps to the rear top bow fell apart, still dealing with that. Window is still holding in strong, just started hitting 115 here in Az. Will see if that lasts.

Hind sight being what it is, buy a BAS top and be done with it. Not sure if they come with the bow straps, but replace those too.

fyi, in a past life I was an auto glass technician so I kinda know a little. Still went thru an entire 100 count box of nitrile gloves, and probably 50 razor blades.

Can it be done? Yes. Should it be done? What’s $850 worth to you?
