The trussed 31spline full floating disk braked 9" is coming out! I need to replace it, but preferably with something nearer stock width this time. With 31" tires, a healthy V8, and only 2900 LB (little of it on the rear ;-) I need a reasonably strong diff, and some kind of traction aid.
options:
I have access to a complete 76EB rearend 3.50LS.
I have an empty 77EB housing
31 spline spool 4.11 pig
28 spline Detroit.
I have the stock 7.5 open 3.45 axle
The 7.5 is going to have to go in for now, to keep rolling.
The main options I'm considering are these:
find an 8.8 ranger rear end, and pop in a Lock Right. gearing isn't a real concern, as long as its in the 3.5 to 4.5:1 range. Mustang T-5 has KILLER overdrive :)

put my locker in the EB 9", and go with it EB width.
Narrow the EB housing 2.5" and buy one more 'short' shaft.
My tires stick out about 3.5" per side with a EB+2.5" width rear end, so the narrowed EB should leave me about an inch out per side. Flare territory.
What to do? I don't think the 7.5 will live very long behind my turbo 4, but once the V8 torque gets to it, its History! Hmmm.. isn't that why I quit v8's in the first place?! hah!

Ford 8.8" is plentiful in Rangers/Explorers, this is the best option.

78 Bronco 351M SM435 NP205, D44 and Ford 9", and all stock!!!

good:
bolt in, correct width.
reasonably priced.

Bad:
28 spline- questionable with my right foot.
(31spline Exploder is not a direct bolt in, and is much more $$...)
C-clip axles- I break a lot of shafts, not the greatest design.
I have a lot of 9" parts kicking around already.
Is the 7.5 and 8.8 Ranger axle the same width, drum to drum?
Is it possible to find a limited slip 8.8 ranger axle complete for under $300? if so perhaps that would make a decent temporary driver, until i build a real axle.
