I've only had MINE in the box for ELEVEN MONTHS, you slacker!!!
I even bought the tape, watched part of it and started screaming....
I haven't asked the guys at Corvette Corner in Rowlett yet. They do most of my stuff I'm too lazy, stupid or afraid to do.
I did check in a conventional body shop - the one next to "M Body Shop" in Mesquite and they gave me an estimate of $275-350 for installation, although they preferred using their material sources.
I loathe body work.
I had the puppy down for nearly six weeks this winter just putting in the supposed drop in digital dash from Nordskog, fixing the vent system, installing a new heater core, repairing all the console/under dash wiring, converting the radio slot to DIN and installing a new one, and putting in wood dash covers.
It took a whole four day weekend to just put in new front carpet and
finally bolt in the late C3 seats the last owners thought would be "trick" (with 2 bolts each....)
Yet I got the dual mount spring installed in two days, without a hitch, despite working under a car on jackstands, which I have a major phobia about.
Always there is something else besides what you went into fix. With the dash mess EVERYTHING was broken - every housing, every vent, every structure. With the carpet there were huge breaks in the fiberglass under the seats, the electric seat was broken and needed mounting rails made to actually adapt it to my model, one underseat metal reinforcement sheet was removed, the rear rib was not rivetted ANYWHERE to the glass and the front pans were so weak I went ahead and added two metal reinforcement plates and a few layers of glass to them too.
If it's not one thing, it's another....
I can't think WHAT can go wrong with the top, but I'm sure there's something... I know what scares me is those staples....all...those.... STAPLES! I still wish one was available with replaceable rear "glass", like a jeep top zipper - that's what was wrong with mine when I bought it.
Oh, the place next to "M Body Shop" says it's just an overnight job. You may try any regular body/interior shop, rather than a corvette specific one. The chains can be iffy though, so be careful. You also want one that doesn't just do dent or collision repair as much as one that does rod and custom work.
