All 8.8" carriers are the same. The only difference is the number of splines on the side gears & the size of the pinion shaft. Most trucks get 31 & the large shaft; most cars get 28 & small. Click my black Bronco in my sig & look thru the 8.8" Axle album.

so then i just need to get the gears out of a P71. i dont even need the shaft (spline shaft?) that the D'shaft bolts to. just take off the 4 bolts and pull it out. well ya take the shafts out first but u get it. if i get the gears out of the one i got the drive shaft some one did most of the work for me cover is off and one half shaft has been pulled.LOL

If you remove the gears from the housing, they have to have to be adjusted. If you use the whole housing you don't need to.

i have a guy who knows how to do it. i just need to get the goods and do most of the work changing them out and he will take it from there.i do know what your saying but brake lines and all the other bulldodo. blah, just swap the inside and go !!

I've done both and I'd prefer the whole unit. The gears once worn in and readjusted for another housing can start whining at certain speeds.

You don't have to mess with brake lines - just remove the calipers & hang them from the body while you swap the whole axle. It's MUCH better, quicker, & cheaper than installing used gears into a different housing.
