I have a 1991 regal with a 3.0 mercruiser engine. While winterizing it today I noticed to large nuts lying in the front of the engine in a small space. Upon further inspection I saw this long threaded bolt which is were they apparently came from. I could barely reach in the crevice and remount them. Is there a special tool available to tighten them properly? And since they came off, would it be a good idea to get the alignment checked?
