Chris,

Thanks for jumping in with your experience with the Dana 60 vs a newer 14 bolt.
Since this is a short bed '72 do not have plans to tow anything heavy. Steve thanks for your second on the good breaking capabilities of the drum Dana 60. What diameter where your rear drums, 11, 12, 13, along with width if you know. Mine are 12x2.5.

This Dana 60 has what seems tobe larger shoes/drums then the original GM '71 size, they are 12x2.5. Have not looked at them for several months, but remember them being 1/2 inch wider then specifications for '71. Previous thread discussed certain GMC / Chevy as having the 2.5 wide drums, and that specs could be wrong, in that original trucks have 2.5 wide shoes. Any information on what were the largest drum brakes for the Dana 60 with stock axle length SRW, what models have them. A thread by Larry on " 11 inch to 13 inch... " also talked about bigger rear brakes, I think his information was on Dana 60 too, not sure. And I will do some research too. May be move the brake discussion to a new thread to make it easier for others to find.


Thanks,
Les

I'm pretty sure they were the larger 13" drums as this rear came from a mid 80's 1 ton but i don't remember what their width was. Very heavy. My 14bolt was a junk yard jewel and the pads and drums needed replaced so i decided to do the disk swap.
