I have a quick question I was hoping everyone could help me with please. I have a friend junking a Buick Regal? not sure on exact model, year is mid/late 90's. I have a 98 GP GT with a 3.8 Series II N/A in need of a motor, and I was wondering what year did Buick go to the same Series II motors, and what models? ANY help would be greatly appreciated.
