I have a PowerMaster brand 180 amp that I just had rebuilt a couple of months ago. I replaced it with a new AC Delco stock style ($110 shipped) and haven't yet put the chrome one back on.
I couldn't sell it for what I have in it, especially with shipping.
I see them at Summit and Jeg's for very similar prices, about $200 with shipping. Might want to try that route. New part with a warranty.......
If it's used, chrome and it's for sale, there's probably a reason.......
As Turbolou always tells me, "Chrome won't get you home."............ Ergo the "rebuilt" part of my comment about the chrome one. It didn't even have 1000 miles on it.
I called summit. They don't have the correct case kit for a turbo buick.
Turbo 6 performance had a kit listed on website but you can't order it. I sent them a message. They said the chrome case has been discontinued.
Looks like we might be S.O.L. on the kit but I think you can buy a complete chrome alternator from them.
