Thanks for your help. It's greatly appreciated. Butternut yellow is fine, but I think other colors suit the cars lines better (no offense LOL). I did'nt think the 4P codes began until the end of Dec. 66. My car was built just prior to that , 12C 3 rd. wk Dec. 66, but anyhow I've checked the rear end code and believe it's from a 68, not a 67. It reads PA0219G2 (PA= 3:08 10 bolt from 67 to 69). The casting date reads B98, which I think relates to Feb. 9th of 68. What do you think? Since I don't have the original motor or trans and its probably not a L30/M20 or an SS, should I have some fun with it? Maybe a 400 HP small block with a 12 bolt and suitable trans? Would it make the car worth any less when finished?
