Default Bubble window on early C3?

Hey all. I'm new to the Corvette world but looking to get a C3 in the near future. Hoping I can learn from the expertise of this forum.

I would love to have the interior cargo space that the bubble window fastbacks (1978-82) have... however I also really like the chrome bumpers and the chrome egg crate side fender vents of the early C3s. I attached photos below of this exact combination - owner is someone by the name of Hans Karlsson.

Anyone know how this hybrid was made? I'm guessing this is an early C3 with a bubble window modification/addition... are these kits readily available? Thanks in advance.

That's not the bubble back glass from 78-82 - looks more like a C2 rear window modification?

Here's an example of a C2 rear window: https://oldcarsguide.com/chevrolet/c...-corvette.html

Agree... a later C2 mod given there's no split window. Would this be a massive pain in the *** to create?

Definitely not a weekend project. If I had to guess, I'd say that the rear deck area was cut out, and a C2 donor car provided the new parts that were grafted in (unless a kit like this was available in the 70's). It definitely looks well done.

The transformation to a 78 - 82 would be MUCH easier. If you could find a donor 82 CE, you'd also gain access to the rear with an opening hatch glass.

C3's lost the chrome egg crate fender vents and chrome bumpers in 73. I believe they were only present 68-72.

Therefore I think this is an early C3... combined with a C2 rear window.

thanks for this... so that likely means the above is a 70-72 vette.

You can glue just about any combination of panels/pieces from any year onto any year.

That's a pretty black car ... and it does seem to be mostly 70-72 ... but I wouldn't begin to guess what year

if you are asking if it can be done, yes. since you are asking, i would strongly recommend you do not attempt it. anybody who can do this wants 100 bucks an hour to do it.
a chrome nose on a 80-82 with the chrome sort-of conversion rear bumper cover is the most doable version. read priya or doorgunner's conversion to get an idea how much work a real 72 tail light panel graft is.

That rear window was called the Riviera Back and was sold through Motion back in the 70's.

Very nice custom. Looks well done and has that looks like it came that way look to it. It seems to me to be a 70-72 with a 64-67 rear deck panel grafted on. 👍😎

And the Riviera with that back window, it was called the corvette back window.

Thats awesome!! Nice find. Guessing there’s no chance to get another one of these kits is there? Quick google search left me with nothing.

Also, what happened to Motion?

What about this rear section? This would provide a similar amount of rear space for you. Kael

Motion’s heyday was in the 70s. They have been gone for decades.

Eckler might have carried those kits for awhile, but probably not these days.
