New Here 76 Cobra Ii

Congratulations on joining the club! Which engine & transmission do you have?

Since it's a 302 it would have the c4 behind it. I don't think there were any bells available to bolt the v8 to a c3 (that was usually used on the 2.3L 4-cylinder).

It doesn't look too hard to find a flexplate for the automatic (double-check these listing as I didn't).

Autozone carries the starter for about $50. RockAuto and a bunch of places online do too. It doesn't hurt to measure the snout-length and the throw of the bendix to make sure it's disengaged when not being cranked and fully engaged when being cranked.

Mechanical parts for the II are largely still available at parts stores and are usually very inexpensive. When you get into interior or body parts that's where the fun begins. Let me know what random parts you need and maybe I can steer you in the right direction.
