T56 trans is tight in a C3 but will fit. If you want the shifter to come out in the stock location, you'll have to do some fab work to offset the handle mount. McLeod used to make an offset shifter that was perfect, but they stopped making it. Not a big loss since it didn't shift very well anyway. (Ask me how I know...)
Anything other than C4 suspension in the rear will require you to cut out the cargo compartments. This really isn't hard to do, but going back original later is out of the question. Battery relocation is another minor issue you'll have to work out.

Above average. I am a welder with many years of custom fabrication experience and have a degree in welding engineering. The closest to this type of job would be prototype and R&D subframes for wreckers (tow trucks) and then building trailers. But I have experience on almost any piece of machinery you find in most shops.
No fiberglass experience at all, that's where my comfort zone ends.

I put a C4 suspension under my '69 several years ago. The biggest issues were simple packaging (trying to make stuff fit under the bodywork) and geometry (bracket locations and front crossmember design).
Just study up on whatever suspension you choose to use, and then keep in mind ways to make the geometry adjustable in case you make an error or just want the car to handle differently in the future.
Good luck, and post some pictures when you start working on it.

Browse the way people have done it before with tube frames. Maybe get an idea for your own mod work on the frame.
Here are a couple:

I was thinking something like this, a full assembly, would be the easiest. It would help with the geometry, leaving only placement and packaging (I really hate the possibility of losing the storage boxes, but I believe the benefits outweigh the cost).
This pic is a 2010 camaro rear suspension.
I am from Australia and the Holden Commodore or Chevrolet SS has a very similar rear end. I have a complete assy from a Commodore SS that I was going to put into a 1977 Holden 1 ton pickup I have with an LS1 4l60e drivetrain, but the powers that be said no can do because of load carrying capacity, we have laws that say because the vehicle was designed to carry 1 ton then the suspension must be applicable, but that's not to say it hasn't been done as it has in these shots.

rear mount
Fabricated crossmember for upper shock mount

right rear from behind
I have had a brief look at the measurements and it looks close but close may not be good enough when it comes down to the nitty gritty.
I'm lazy by nature and would rather follow someone else's lead on this.
Cheers.
