Coley detailed it best. kinda what i was hinting at but he did a much better job of detailing it.
As far as the 307, i personally am not a fan of 307, but BUT if you need to figure out what you want, original rebuild or modify. modify will allow you to alter things easily, but original can be very cool. The original factory AC is awesome. so just a few more things you need to figure out.
Good luck, best thing is that you have a great start!
