Re: value of dana 300
IH Dana 300's are worth money. I don't have the price sheet handy (still packed), but I believe Anything Scout sells rebuilt Dana 300's for like $600. If you can get it cheap, it's definitely worth rebuilding and selling...while I for one wouldn't sell it at that price, you can almost definitely get more money for it than what you put into it. Good luck!
