dually rear end question

ok folks, for years i have been told that a dually rear end is 7/9 inches wider than a regular 3/4 -1ton truck , pick-up not cab chassis. Here,s what i have a 1993 ccdrw 1 ton . i can get a 1999 f250 4x4 cc srw pick-up. i just measured the rear -end from brake mounting flange, and both rear-ends are within a 1/4 inche of each other. could someone please explain this? rusty

The OBS DRW pickup 10.25 is about 4" wider per side than a SRW 10.25 from memory. On the SRW OBS trucks, the rear was about 2" narrower than a D60 front. The 99 axle is a 10.5 with disk brakes and is closer to the same width as the front axle than the OBS. On the 99 axle, the lug pattern changed and likely the width and backspacing of the wheels too. Hubs are shorter on the 10.5 vs the 10.25. Are you trying to replace a DRW 10.25 with a SRW 10.5? Sorry I don't have dimentions but your compairing some vary different axles.
