help with 66 valiant rear axle

This should show you how I did mine, and I do believe if you want to change the rear end out anything up to 73 A body will fit, but remember, you will need U-Bolts if it is a 8 1/4 rear end, yoke,, but finding another 7 1/4 it is possible that it will need this dun as well, I elected to check my problem out and repair it.
I am not a good tec, But! I am sure one will jump in here and guide you soon..Here is pictures and read what problems I ran into page 19 in my restoration thread here http://www.forabodiesonly.com/mopar/showthread.php?t=41794&page=19 and there is a 66 Valint/dart manual you can down loud here .
