Hey so I have been on a hunt for a t56 or t10. So the only thing I'v been able to find for a decent price in nevada is a t10 from a 63 ford falcon. my question is will it fit in a 3rd gen camaro?

Transmission, maybe. Bellhousing, no.

Why would you even want a T10? Unless your car was originally equipped with one (highly unlikely), you'll need to swap out all the pieces you would need to with a T56. By the time it's all said and done, you'll have spent as much as you would swapping in the 6-speed, and be left with a sloppy shifting 4-speed and can't take the car on long trips.

No.

Bolt pattern to the BH is different, mount is different, splines on the clutch are different, drive shaft is different, finding a BH (unless you go $$$aftermarket$$$) is EXTREMELY tough (one-year-only: only 82 will fit, along with ALL of its associated parts), shifter near impossible to find any more, no torque arm mount.

Not a good candidate. "Possible" for those who are willing to do considerable fabrication, adaptation, and other monkey-motion; FAR from bolt-in. One of those "if you have to ask, it's not for you" type things.
