ABRACADABRA, has always been a favorite for me...
Seriously though you will need several things you currently do not have on your car.
1: A Manual Tranny
2: A Maverick Clutch Quadrant and pedal and linkage etc...
3: Manual Transmission crossmember
4: Flywheel
5: Clutch Set
6: Pilot Shaft Bearing
7: Clutch return spring
8: Manual Transmission Shifter (for what ever style tranny you pick, the shifter must match, and there are a lot of them...)
9: Manual tranny shift Linkage
10: Gotta remove the front seats and carpet
11: Cut hole in floor for linkage...
The list goes on and on and you will need in excess of $1,000 bucks to do all this... Unless you find a donor car to get the majority of your parts off of.
The tranny will cost you $500 to $1,000 depending on what you want....
Good Luck!
