Window effing regulator

Where the hell can i get the original regulator for the 2d driverside window? Everyone is selling the damn doorman version, do i have to cross over to that one? i want to keep the one with the black motor not the silver one. Or does it not matter???



oh yeah and my rpm's are jumping what's that about??? the only jump like once a week but it jumps between 500 an 1000 it rarley ever just dies but it's still annoying as hell
and my car bounces a bit when i take off to fast if feels like the tires don't have good traction but i think
something maybe wrong with my transmission kindda hard to determine cause im in the car i cant see if it's the '
tires or not.
