My son's engine died in his 98 Mustang Base with v6 3.8L automatic. We are looking for used engines on the net to see if we can swap it out. What problems would we run into if we pulled the engine out and replaced it with a 3.8L out of a 95 Mustang? I found one that is already pulled. The seller states that it has the ODBII connection. What all should we be looking for? Would this engine work in his 98? Thank you!
