I have the rear gears (8.8) that are a 4.10 ratio. They come with the pinion and are on a Limited Slip provider. I also have the matching front ratio that is in the 3rd member from a 1992 F-150 (D44 TTB front axle).
These equipments will certainly fit any F150/Bronco from 1. They will also fit other 31 spline 8.8. If you've swapped in one to a ranger from an explorer or mustang and so on. I drew them from the 1992 150 because it was sitting, had been for 6 years (equipments hardly used at all) with the intent of putting them in my Bronco. Well the Broncos for sale, so I'm not putting these in it anymore.
I just need them gone, I'll even deliver them in your area ... Tired of looking at them in my shed!
** Just the equipments, not the full axle *.
