Goofy 8 3/4 ID

[wagonman]

So I picked up a Crusty 8 3/4 for cheep, supposed to be out of an A-body NOT. It is complete drum to drum with a 741 case and a 3.91 tag, looks to have never been apart. Tore it down to a bare housing and started measuring. I used the sticky chart as a reference. Here goes, flange to flange is 59in. Axle lenght is 31 1/4 spring perches are 44in. And 11x2 drums. I am kinda thinking a truck app but the 44 perches have me scratching my head. WTH dose this thing fit?

Likely a C or E body rear. Truck apps would have the perches on top of the housing as opposed to the bottom.

Looks like you nailed it, did a compare with my 68 Runner and the perches are on top of Crusty Goofy. Many thanks.

MyMopar B-body says 59.2" flange to flange and 44" perches.

The 8 3/4 truck rear is somewhat desirable as it will bolt into full size ram trucks into the early 90's

Put one from a 66 into my 79 years ago.....just had to swap out E brake cables and that was it.

Narrow that thing to what you need, get new axles/perches, your set.
