It's not hard at all. If you look through my posts you will find one that well actually like 50 that I have covered this topic. Search!!!!!!!!!!
But really it's not that hard. Rip the auto shifter out and the plate that is under it. Could be a bit of a pain but it's simple shit. Remove auto tranny, torque converter plate. and that's it.
Here is where it starts getting fun.
Install clucth pedal
Install hydro lines to tranny
Install your fly wheel ( with the new 5speed studs) auto ones are too short
Install clutch
replace rear t bracket
replace half shaft
Mount tranny to the engine
Use the auto to 5speed hasport mount
Install torque mount and bracket in front
Install shift linkage. There will be 2 holes where the old shifter is (use those)
Jump the 2 big wires on the auto shifter harness (can't remember the colors) but there is only 2 fat ones on the harness
Run wires for your reverse lights
Swap ecu's but you dont really need too.
Axels are the same (don't let anyone tell you diffrent) and thats it.
You can also use your auto halfshaft but you will need some washers and it's not that safe.
Goodluck .
Seems harder then what it is.
