Thanks guys for the advice. GV is big bucks. I like the 518 idea but the only thing that would scare me is cutting the bellhousing. Everything else no problem. It is a Dodge M500 chassis. Loads of room to make anything fit. The only issue I could see is having to lose the Ebrake brake on the driveshaft which does not work anyway and was a joke when it did.Might as well nail an old shoe to a stick and call the the emergency brake shoe.
I'd like more info on the 518 bellhousing swap and cutting the 518. Everything else I can handle . I can have the driveshaft modded up the street and I am a welder.
