Are all 3rd gen trans am T tops compatible?

Not quite. 1982-1984 t-tops have a hook style latching system. 1985 to 1992 cars use a pin style latching system to hold the t-tops in place.

Also the pin styles vary in diameter depending on year

Do they? I knew there were other differences such as mirror vs. non-mirroed finish, tint differences and of course the outer weather stripping on 90+ cars.

There are some differences in t-tops. They could be glass or lexan, which you should be able to just adjust the mounts and they will work. Also I believe the newer years 90-92 have bigger pins that hold the tops in place but that wouldn't be a problem if you can get the plastic mounts behind the A and B pillar moldings and switch those over as well.

yea..theres some that are like pencil sized then theres some that are like kindergarden crayon size

the ones on my 85 are about kindergarten crayon size...but they don't leak...and I sprayed a hose at em! lol!

I've got an '84 Berlinetta, it's pin style with large diameter pins. This isn't stock? The tops have the Vin scribed into them though.

Don't forget the aftermarket T-Tops..

My '83 has C&C T-tops that are a different size then factory ones.

My 83 Camaro has a C&C T-tops, any suggestion on where I can buy replacement weather stripping for it?

As far as I know no one makes weather stripping for C&C T-Top cars.

They have C&C weather stripping.

sorry to thread jack but any idea of who or how much it would run me to t-top my hardtop. ive got 2 firebirds, one i keep completley original and the other is just a mod car. But i dont know where to even start to find someone to cut the roof out.

get a t-top roof assembly from a j-yard and use it to replace your hardtop.
