Thanks for everyone's advice.
I am going to go for it. I saw it this afternoon and it is in excellent condition. It was rebuilt not to long ago. I believe am coming out of this deal looking good.
I am not going to do this work myself, I know this is way out of my league. I have a buddy who knows rear ends and has some connections.
It has got 411 gears in it now so I will eventually need to change over to 373. Looks like new gear sets are easy to get a hold of.
Since it is so much work to relocate the spring perches and shock mounts, I am thinking about installing a 4 link. (The company I am getting my IFS from has a great package deal.) I still have lots of research to do before I go with this option.
Well, thanks again for everyone's feedback.
