Well I'm looking in the book and I have 83-86 PA302 and 87+ PA305. For some reason I'm based on HKT part numbers, they probably had the best catalog. I have some pretty good cross-reference info here that I put into a spreadsheet.
PA302 is also AC8G, CH80, WAP 80/88.
PA305 is also AC13G, CH84, or WAP 84.
With that said, was your 86 early or late 86?
