5 spd. conversion thread

I am glad u took the time to post this build. I am kicking around putting in a 5 speed or building a nasty 904. I am a Stick guy so a 5 speed is my perfect choice but the cutting and welding to a 1 of 4 car, scares the hell out of me. What rear end gear are u using and what is the rpm at 75 mph ? Tire size would matter also.. Thanks
