By the way, what bonding adhesive did you use. Also for any of you true convertible owners out there, the convertible clip has a rectangular hole on the upper part of the door jam, but the my coupe clip does not. Does anyone know what this is for?
That rectangular hole is for your convertible wedge pins and guides to make the body more rigid when the doors are closed. You can add them if you want but they are expensive so I left them off of my 72 and can't notice the difference. They didn't use them on the earlier C3 convertibles.

Thanks BJ, that's interesting to know. Finished cleaning up all the brackets and mounts, and temporarily installed the decklid hinges. Tomorrow I'll see about installing and adjusting the decklid release latches. That 3m panel adhesive looks like hi tech and expensive stuff. The bonding strip adhesive I have been removing with the hheat gun, looks more like crappy 'ol bondo.

Looking good!

So that's what my deck lid looked like before the previous owner glassed over the edges and sealed it off!

Looks great. As far as the 3m product goes, I tend to go over board. Bondo probably will do the job.

Read every post I could find and took note of all the warnings, ignoring most of them. I plan on using as little of the convertible rear clip as possible. So I plan on making my own bonding strips from unused panels. Removed the spare holder and gas tank, and installed a half gallon tank under the hood, so I can still drive it around. Making that first cut was scary and I said to myself "what the hell am I doing". But as I go I'm feeling better and better. Unbonding panels is slow going but the heat gun does the job. I am finding that the coupe body has almost all the same indentations and rivet holes for the convertible parts. The hardest part so far has been cutting through the spot welds behind the door jams, some were at bad angels and had to use the nasty air hammer on a few of them. I'm at the point I know what to do, how to mount the deck hings, the latch catches, the guide pins, what to bond and where. I'm sure there will be lots of other issues as I go, but nothing seems insurmountable. This is where I am at after 3 days work.
I like the idea, when I bought my vette, I originally wanted a 67 bigblock, went to a corvette dealer most problem heard of them, it was visone corvette, they maybe had 100 vettes in the showroom mostly 60-70's I seen my black on black 67, sales manager opened the hood I seen that big block, and I said to myself I couldn't afford the payments and have to build the motor, I just knew my luck.. so I turned away from my dream car. looked at 2 other vettes both 74, one was a 74 l-82 coupe and the other 74 covertible with a l-48, again I thought my luck, my car will be to easy to access for theives with a convertible..so I got the coupe, and today I wish I bought the convertible, that was 26 years ago,,, ok, I really wish I got the 67.. by the way I ended up rebuilding the L-82 just two years later, but that I could afford..

So bust out the sawzall and go to town!!! Apparently every coupe has an inner convertible. It just needs to be set free!

It's kinda neat, as you start to tear things apart you see how it was put together and at what point in its assmbly the the coupe and convertible were the same. Anyway, installed the latches and am beginning to test fit. It been a kind of a catch 22, you can't bond down the rear panel until you makes sure it is in position. You cant latch the decklid until the rear panel is in place. You move the hinge postiion a bit,then you gotta reposition the decklid. then the latch is off and needs to be readjusted. My main concern is bonding in the piece that support the top of the hinge. I'm think I'm going to install some temporary 1/4" bolts, cause once it'sb onded in place, it's there to stay.

My '72 vert has FI on it, and so to have a special starting sequence, don't follow it, and car sits......only way to steal my car is tow it......

upon repainting it some years ago, I even removed the door locks, no sense to lock a vert......

Got the rear deck bonded down today. Made bonding strips from some old body panels, secured them to the body, and bonded the rear deck. Used plenty of clamps, and now it's nice and solid. Ugly from the top side, but solid. This weekend, I'll bolt down the decklid and hopefully it will fit and latch properly. If all goes well, the the hardest part is behind me.

Has anyone mentioned that a convertible needs a metal saddle bonded to the tunnel and that there are four additional under dash braces?
You know the 68 coupes were called "convertible-coupes" in the brochures. Lou.

It was a good day, after some adjustments, the decklid latches, panel fit is good. Had to take it for a short ride round the neighborhood. Man it made me feel like I was 17 again. Shifting gears, hearing the exhaust behind, wind in the face. No rattles, no cowl shake. It's like an entirely different car. The worst is part behind me, now just lots and lots and lots of small jobs and details, not to mention body work and paint.
