I did this same thing a few years ago. It's really quite simple. I bought a swap kit form mustang parts specialties, it had everything needed to swap. You can do the same, or find a junkyard car and pull the 5-spd yourself. Also you'll get a bit of practice while you're at it. I had never attempted anything like that before, so I did some research. i got a Haynes manual and read about installing a clutch, and the like. I also asked around to some of the "old guys" I worked with. And the big thing, make sure you got good tools. A nice long extension, swivel socket, and torque wrench are often overlooked. The hard parts included putting the pedal assy. in, and movig the heavy auto. around. Need anything else, just ask, good luck
