Best place to find most of what you would need would be a junk yard, if you can find a floor mounted shifter in one. The rest of it could likly be found at
www.yearone.com they carry a lot of trim and peices.
Could also get an aftermatket shifter from B&M, they make tons of them, and they work pretty good. You can find most of them at
