Gentlemen,

How much of a pain would it be to install fasteners/snaps for a full tonneau? The builder of my car decided not to install it during the build process. I certainly like the idea of closing the interior when parked outside - Keeps the roaming hands away.

I'm assuming that the two outer and two inner(rearview mirror post) fasteners, and just a matter of matching up the snaps to the existing ones on the back. Would I need to remove the windshield in the process?

Thanks - Mel
I had a full on my car before I took it to the body shop and had some snaps removed. There were a series of snaps along the inside of the bottom of the windshield. The full tonneau had a zip down the middle that would open just past the seat so you could drive with the tonneau on. I removed it and use the full tonneau as a quarter tonneau.

Mel - The CMC directions say to drill and attach snaps before installing the windshield. If you have a Dremell tool (or one of those flexible shafts that connects to a drill motor) - ya might be able to mark where they go with a small drill from top and then if you can get around the wiring and other under dash stuff - ya might be able to drill a straight hole up from below and attach smap with a small stainless steel screw and nut. Removing a properly fitting windshield is risky --- get it too tight on reinstall and ya buy a new one!
Mel:

While it's possible to install those snaps just inside of the windshield without removing the windshield by drilling UP from below (I did it on mine), it is a Mega-Major pain in the ass, AND you're pushing UP against the gel and paint coats so that when you contact the gel coat with your drill, chances are you'll push a BIG gel chip up off the dash - not exactly cool. You can get around this a bit if you have a semi-soft piece of rubber to push down hard on the dash exactly above the drill exit point, but it's still iffy at best.

I would strongly recommend removing the windshield, installing the snap receptacles from above, then re-installing the windshield. Remember to use a relatively dull dril and run it slowly with light pressure so as not to chip the paint/gel coat.

BTW: without going out in the garage to look, I have only three snaps on each side at the front, NOT the "one-snap-every-5-inches" the CMC manual recommends. One an inch away on each side of the center support, one about mid-way to the end and one just behind the windshield corner post.....that's it, and works fine.

Good point - I didn't have a vinyl cover on my dash when I drilled those holes (still don't, as a matter of fact).

I remember that I did one with a Dremel, but switched to a regular variable-speed drill on a low speed setting for the rest (with very gentle drill pressure).

A neat trick for drilling through both threaded-back vinyl material OR carpeting, without pulling the threads or carpet strands, is to dip your drill bit into Johnson's Hardwood Floor Wax just before you start drilling. This really works - I learned this in a prior life as a car stereo installer.

Yes, believe me, this trick really works. I keep a can of Johnson's Floor wax in the shop just for that sort of thing. I must have installed over 100 car stereo's as a co-op job in college and never had a pull when I used it. If I forgot, or got lazy, then that's another matter.

Just dip it in the length of the drill bit, don't wipe it off or anything, just start drilling. Re-dip for the next hole and so forth.

I took a look at the space I had to work with. Coming in from the top, Dremel with the flex attachment was still a little tight. I might have some room if I back it out a bit from the exact location.

I looked underneath and that just makes me too nervous trying to negotiate the space. I don't think I could line it up evenly, let alone worry about chipping fiberglass and tearing vinyl.

Removing the windshield would be the proper way to go.

I'll have to think about how bad I want this option.

Thanks for the help as always - Mel
I would go with the pull the windshield option. It is a simple proceedure:

Remove the center support rod nut that is under the dash, leave the rod attached to the windshield frame ... ( it can't be easily removed from the frame at this time unless the dash hole is larger that the rod diameter)
Remove the four screws on the windshield posts, have someone help you by "gently" ...lifting the windshield assembly evenly about 2" to 3" away from the body , once the center rod has cleared the top of the dash, then pull the center support rod up 1/16" to release it from the top windshield frame.

Alan:

Why not leave the windshield frame attached to the corner posts and just remove the nuts from the posts below the dash and lift the whole thing (windshield frame, posts and all) right off, then gently lift off the windshield?? It would seem easier to remove the posts than to remove the frame screws from the posts (and then have to fight to get them back in on re-installation as there is a tiny bit of tension there.

This is about the opposite to what I did to install it, and it seemed to work OK, although I have very little downward "pull" on that frame - the windshield is almost floating, it's so loose.

Of course, I might find out that I installed it wrong in the first place!!
