Should have said. It won't
"FIT" mine or I would have bought it.
I need to point out one major factor.This cluster is soley used in the 1985 cavalier as far as I KNOW! I know gm was all wishy wash but based on my yard parting this is a very specific design as the sunny has this.If I could afford to buy it up it would be in the works.With the loads of money already tied up in the recent updates it kind of cut into my budget for extras right now.Still minty fresh back up yeap I could always use more parts.
It was also in 86-88 RS models. My former '86 has this cluster, I pulled one out of an 87 RS ragtop many years ago and it appeared in the literature for the 88 RS coupe that I saw since they kept the same dash into the first year of the 2nd gen J-cars. Good find regardless.
Daryl is correct.
I pulled out my beloved 1986 Dealer Catalog and by golly it does show this IC for the RS
...had a terrible time getting photos because the pages are really shiny - like brand new.
