I have 2 alternators from my Northstar but are basically LS type alternators. had them rebuilt by a rebuild specialist here in Vegas. Have used his stuff for years and never had an issue. one is a 2 wire set-up and the other is a 1 wire. Both are 140 amp alternators. Pics on request $45.00 each will ship on your dime or glamis postal to so cal or PHX.
