The 14-bolt came out in '73 and ran till... I dunno. A really long time, too . Without checking, I believe the HO rears began use in '38 or so. Maybe early '40s |
The full floater 10.5” 14 bolt as we know it is still made by AAM for use in GM 3/4 ton trucks with out the Duramax. My ‘18 Sierra 2500 has one. The biggest change is the addition of disk brakes. Not to be confused with the 11.5” 14 bolt used in the duramax and ram trucks which is similar but not the same.
