Quick question, need an answer ASAP

I'm looking for a turbocharger from a Buick GN, and I had a question. I've heard that some of the stock turbochargers had .60/.63 A/R and some had .43 A/R. What years had the .60?

86-87 had .60/.63 not sure about 84-85

I have a rebuildable core if interested. 50 bucks plus shipping
