I was just wondering because I'm in Tassie, and have a 202 red motor with a 4 speed box which would be perfect for you, if you didn't want to rebuild the motor you were planning on using. I've got a 78 HZ Kingswood. I'm making mine how I want it, similar to you I guess. It was originally white with a buckskin interior, 202 four on the floor. I'm putting a full black GTS interior in mine, getting it sprayed either nocturne blue or windsor blue. Because I'm in Tasmania, I'm allowed to have a V8 on my L's and P's.
