I have several questions for you 14Bff experts, especially those with real world experience. My 10B is loosing a wheel bearing and it's time to swap in the 14Bff that I have been saving for just such an occasion. 1) Does anyone make and sell a Full Spool (complete carrier) for the 14Bff 10.5" Ring Gear. 2) Does anyone make and sell a Mini Spool (replaces spider and side gears in an open diff carrier) for the 14Bff 10.5" Ring Gear. I have seen one advertised, but it's not yet available. 3) Has anyone had experience with and used Grady's 14Bff 6061 T6 Aluminum FF Hubs. They are available in 6 0n 5.5" but are the available in other configurations like 5 on 5.5"? How much Track Width if any do they add? Do they require custom axles or axle mods? 4) Is anyone using or familiar with any Alloy Axles for the 14Bff 10.5" Ring Gear. 5) Can anyone confirm the part number for the conversion U-Joint when swapping in a 14Bff for a 10B in a '90 Blazer? I believe it is a Neapco 2-1153 or a NAPA #447. Is any other driveline modification (lengthening/shortening) needed when making this swap? I appreciate your help and expertise!
