I have an 84 firebird that started out as a v6, but now has a built 355 in it. The previous owner was the one that set it all up and I have no clue what clutch to get. It has a Borg Warner 5 speed and the Codes from it are 13-52-066-925 R3. I took it to a shop but theres some confusion as to how many splines the clutch should have. anyone know?

 

Does anyone atleast know a site or program where I could look up the code?

 

Do you know what car the 5 speed came out of?

 

No idea. I know it's an original 5 speed car, doubt it would be the original tranny but you never know until you pull it apart and I can't really do that now cause it's my daily driver
