hmmm my 50 has an open driveline.... and 5.14 in the rear end...
Don't fret there are deals here too. It just takes patience. And cash. Set the money, you want to spend, aside. When you find a truck find someone to look it over with you if you aren't sure that you have all the info you'd like to have. Or look and post questions here. These folks are handy to have around!
I'll keep an eye out for one for ya, I seem to trip over them from time to time.
