I just about finished up swapping out a 10 bolt rear end in my 2000 silverado with a aam 11.5 14 bolt rear end from and 03 3/4hd duramax. the axle tubes on the aam are 3.5" and the 10 bolt was 3" i think. I'm trying to find where i can get the bottom brackets that the u-bolts bolt though but i'm not sure what they are called.

 

Axle U-bolt saddle bracket

 

Ah, a saddle bracket seems so simple now. any idea where i might be able to order these?

 

If you are looking for a stock one,a junkyard would prolly be the best place to look.

 

They include them for free when you purchase a new set of Cal-Tracs.

 

Dealer as well obviously....I dont know if a yard would sell them to you without the whole leaf spring or axle or something. Unless you happen to find one in a "you pull it" in which case that truck will probably be too new to find there.
