Guys, you can go purchase 4 starter bolts and install them in the transmission to engine and use them to slide the trasmission back to install the converter. This is much easier when you go stab it back up cause the bolts keep the tranny aligned. Will have to take off the Y pipe to let the engine hang on cameros...not enough room to slide back. Works great on a truck!
Make sure you get the coverter installed all the way, usually 2 'clunks' heard/felt...you should not be able to put your fingers behind the converter on the sides...close clearance.
