Is there any other cars that use the same rear end size and setup?
What year?
Will it bolt in?
(we have a shortage of camaros here cuz a guy buys them all and parts them out for insane prices)

The only differential that will "bolt in" to a third gen is out of another third gen. The same goes for axles. Third gen axles are the only ones that length.
Third gens use a 7 1/2"/ 7 5/8" ring gear. Those are common to GM cars since the late 70's. Many G-body cars have them. S-10's also use that size so the carrier and gears can be found easily.
Around 1986 GM switched from 7 1/2" to 7 5/8". Both will fit on the same carrier.
In 1990 GM started using 28 spline axles. Before that they were 26 spline. You can put 28 spline axles from a 90-92 third gen into any other third gen as long as the carrier is changed for the 28 splines.
Fourth gen diffs are a direct swap into a third gen however the diff is 2" wider per side so proper backspaced rims are required or your stock rims will stick out too much.
The other option is to buy an aftermarket bolt in diff. A complete 9" or 12 bolt will set you back around $2000 US.
What exactly are you looking for? I have a 10 bolt housing with disk brakes for sale. No axles or carrier. I can supply aftermarket 28 spline axles for it and 4.10 gears. I have no carrier for it.
I also have a complete 1987 9 bolt with disk brakes, posi and 3.27 gears. It's much stronger than a 10 bolt.

Come to Calgary and go through Pick-Your-Part. I've seen third gens in there that still have diffs in them. I've only seen one with a posi and one with disk brakes but they disappeared within days. I "think" a complete diff is $150 but it could be cheaper. It's been a while since I last bought a complete diff there.

The only other self help yard is Bucks (Cheap Charlies/Navaho metals). It's not as nice as PYP.
I've seen a few 400's. I pulled one from a Van a few years ago.
If you want to put a production 9" under the car you need to either change the rear suspension or find some way to attach the torque arm. The 9" under my race car came from a 1970 F100. The housing is almost the same width but close enough to use. I already had a center section with 4.56 gears and a spool. I had to order aftermarket axles though. Ford truck bolt pattern is huge. I installed the large ford drum brakes on the car and they work fine. My rims are dual bolt pattern so using the ford bolt pattern wasn't a problem. I changed my suspension to ladder bars to make the swap easier but I don't recommend ladder bars for a street car.

what I am planning is to take, measure and make a jig of the camaro rear end, and then cut the mounts off it when I find a 9 inch with axels that is the right size... Then I can weld the mounts on and have a 9 inch... I know it works the guy who is helping me with this has done it before....
I am looking at buying a 400 right now in edmonton but the guy isn't getting me the casting numbers very fast... I also need to find a cheap t-56 somewhere...
I am 17 so these are like 3 year plans but basically you get what I am doing with my car (daily driver now, toy when I get out of university)

You can easily move over the shock, spring and LCA mounts from a 10 bolt on to a 9" but like I mentioned above you still need to find some way to attach the torque arm.
Moser or Currie, I can't remember which one, will sell you a torque arm mount that can be welded onto a 9" housing. It's $150 US.

Donor vehicles with 9" housings that are close enough to use in a third gen are;
57-72 F-100 Pickup
60-64 Ford
64-71 Full size cars
70-73 Mustang Family (yah right, good luck finding a 9" from them)
Diffs that are a couple of inches narrower;
57-59 Ford
57-59 Ranchero or station wagons
79-81 Lincoln Versailles
66-77 Bronco
77-81 Granada/Versailles
67-70 Mustang/Cougar/Fairlane/Comet/Falcon
Diffs that a couple of inches wider;
72-79 Ford intermediate & Full Size
70-79 Ranchero/Torino
Diffs that are just too wide;
73-86 F-150 Pickup
78-86 Bronco
77-86 Ford E-150
That should help you track down a 9" or at least something to go looking for. The car diffs are better since they have a bolt pattern that you could easily use with some aftermarket rims. The pinion will also be centered under the car better than a truck diff.
Not all these cars came with a 9". Many only have an 8.8". Many also have terrible gears. I saw a 460 Cougar with 2.73 gears in it.
