Here, let me fiddle with the choke and try another yank.
"60"s- Round Chevelle taillights. GSX chin spoiler. 442 hood scoops. GTO Endura bumpers. I realize those are mostly 70s items but they fit my criteria for the late era.
I'm not old enough for the other eras but the concept could apply to each time window and one may make more sense than the other once I hear other opinions. I want to dream up rides that incorporate the best, most distinct and unique brand features on one car and call it chevroldsmobuiac. More of a design exercise than a build idea but you never know.
