Camaro is the same but you probably knew that. I have one that was professionally rebuilt, picked it up at a vendor's booth at a swap meet. I ended up going with an auto instead so I didn’t use it. I sold all the manual tranny stuff not specific to the 3 speed but I still have the shifter. Pics are here in the old thread. I can take some more if you are interested. I think I paid $125 and I know I bought the ball separate. https://firstgenfirebird.org/forums/ubbthreads.php?ubb=showflat&Number=245132
