Neighbor has a 91 Firebird. He replaced his starter but the problem he has is that on the solenoid he has 2 small protruding bolt and 2 large protruding bolt. The small we figured out but not the 2 large one. I am guessing that ont he large bolt, it goes to the one which has a wire connected to it to the starter. He tried calling hte store where he purchased the item but they were closed. I've never seen a solenoid/starter set up like the one I saw today. He was told that it was the correct one. Any help would be appreciated.
