4 speed ka-booom !

That is EXACTLY why everyone is suggesting you put a auto in there. You WONT keep the drivetrain together using what you have, your just gonna keep breaking parts until you wake up one day and realize you spent more breaking stock parts than it would have cost to buy good stuff ONE time! I understand your enthusiasm though, just look at the big picture and do it right the first time. Love your car and what your doing, just offering one guys opinion....
