Has Anyone Ever Tried To Use A Explorer 8.8 Rear In Their A Body?
There Are Lots Of Them In Salvage Yards With Posi Due To The 4500. Buyout. They Are Not Near As Strong As A 8 3/4 But Ford Lovers Think They Are A Good Unit. Maybe There Is No Chance That They Would Fit, Just An Idea. They Have To Be Better Than My 7 1/4.

Here's the downlow on them:

Ford 8.8 specs:
Weight (complete assembly w/ brakes etc.): 174 lb.
Drivers side Ford brake hose #: F5TZ-2282-A
Passenger side brake hose #: XL2Z-2282-AA
Bolt size (U-joint flange to yoke) is: 12 x 1.75 x 30 mm

Axle shaft Strength and output torque rating by Warn and 4 Wheeler
(thanks joe and Chile99.)

The axle shaft strength (tested by Warn Ind.) is as follows:
F8.8= 6,500 (lb. ft.)
D44= 4,600-5,000 (lb. ft.)
D35C= 4,000-4,300 (lb. ft.)

COT: Continuous output torque rating
MOT: Maximum output torque rating
Numbers from January edition of Fourwheeler, page 60.
Dana 35 rear axle COT: 870 MOT: 3480
Dana 44 rear axle COT: 1100 MOT: 4460
Ford 8.8 28spline COT: 1250 MOT: 4600
Ford 8.8 31spline COT: 1360 MOT: 5100
Dana60 semifloat COT: 1500 MOT: 5500

Measurements:
O.D. of tubes: 3.250".
Tube thickness: .250" (some are .188”!)
Ring gear diameter: 8.800".
Ring gear bolts: 7/16" dia. (qty. 10).
Pinion diameter/splines: 1.625 / 30.
Axle shaft/splines: 1.320 / 31.
Rotor thickness (where it mounts to axle is .250").
Overall width* 59.625" (the F8.8 is .950" narrower then a TJ Dana 35).
Hole diameter for ABS sensor in top of housing: .811".
Centerline of housing to C/L of pinion difference is 3.875" toward the P/S.
Pinion offset: P/S to C/L of Pinion, 27-3/4" (no rotor on axle), D/S to C/L of Pinion, 31-5/8" (no rotor on axle). (this measurement is 2.5" more offset to the P/S then a TJ Dana 35).
 
They use a c-clip to retain the axle so that alone is one reason not to go with one. I think I recall that they are quite a bit wider also. If I recall about 3"-5" wider. They do have disc brakes on most and a 5X4.5 bolt pattern. I am using the rear discs from an explorer on my narrowed 9" going in the dart (shame on me). They will bolt right up and are a cheap upgrade over drums.
 
if i remember right there are about the hub to hub as the b_body 8.75 i do know the bolt right in my 48 dodge coupe and work well
 
it will fit i know of a 1975 dart that has one in it i just installed a 66 b-body 8-3/4 in my 67 dart just moved perchs 15 x 8 with 51/2 back spaceing wheels you can use the same wheels with the 8.8
 
Thanks, My Cousin In Detroit Thinks He Will Be Able To Get One At A Pull It Yourself Yard For $75. I Think I Will Pass On It. He Also Has The Equipt And Experience To Cut Down A B Body Rear So I May Go That Way. They Turn Up Around Here On In A While. I Just Looked
At One The Guy Said Was Out Of A 68 Satalite 318. It Looked Like 7 1/4 Only Bigger. Maybe 8 1/4?
 
8.8's are plenty strong!! The one in my son's blue Mustang has been in it for many years, with nothing more than Moser C-clip eliminator 31 spline axles and a Spool.(6.55 @ 103 1/8th mile) Most Explorers came with 3.73's and posi, and there are tons of them in the salvage yards.8)
