Fair enough..... Just remembered this one.... you need to get a hold of this guy.... "Bus Grease Monkey". He messes with, and helps people that have the equally dreaded "restore an old MCI bus into a motorhome" disease. They all have DD's in the back. He's VERY good, and seems to be in it for the love and not so much for the money. He's actually done a few boat motors too..... There's a LOT of videos. Watch a few and you'll get the idea.
