Well the rear end (C&C) that my wheels came off of is still available and I intend to go get some measurements as soon as I can break away from home. It's about 80 miles away and between working a lot of OT at work and the demands of a family I've been quite busy.
Seems like sometimes time is a more precious commodity than money. Hopefully next weekend I can sneak away and go measure it.
Thanks for all the advice.
On a side note, I took a load of brush and junk to the big dump we have here. Two separate times guys asked my if I was interested in selling my truck. Made me feel proud of the ol'rusty girl.
