Looking for a 7.25 rear end for a 69 barracuda

Got a couple of them in Rockford, IL but you have to removed one of them...
If you feel like driving to Ann Arbor, Mi., you can have one out of the 69 Cuda I'm parting out for free!
i will be in Ann Arbor the second week of April but it is for business and I will be driving a rental car but will be returning in the end of June with my truck this time could pick it up than. Do you know if it is a good rear end? That was the problem with mine it sat for so long I think moisture got to the ring gear and is very noisy now. Let me know
