personally dont see how 1 tooth off makes such a difference, say does yours have a clip tyoe distributor or a cap ith 2 screws? my 1987 and 1982 had different caps. the 87 had a clip distributor, but the 82 had the screw in and i nearly stripped the screws getting it out. going with 87 distributor.

just a heads up to gen 1 owners if the gen 2 had a clip type.
