i have both a D44 and a 14FF that have 3.73 in them. i knowthat the carrier break for the D44 is 3.73 and for the 14FF is 4.11. if i get new carriers on the higher side i can put 5.13's in right? Grant 1974 Chevy Blazer Cheyanne. but it is on 33's now, with saggy old springs. i am in Yuma Arizona if ya got any parts for me.
