If you don't have time to do it right will you have time to do it over?
I suspect no one else has done this, I had an 8.8 that turned out to be junk except for the housing and the axle pads were welded on the housing at 2 different angles-both wrong. I have a stock of parts for the Mustang II I've owned for 30 years so I measured the axle width for the heck of it. A Mustang II rear axle is 1/4" wider than the 91 Ranger rear end that was in my 93. I had a new Yukon limited slip that was for my Mustang, a variety of gears, and assorted hardware. I was able to build a new 8" rear after buying a bearing and seal kit, new wheel bearings, and axle seals. Currie made me a pair of 5 lug axles(about $500) and the 10" Ranger backing plates bolted right up to the Mustang II housing like they were made for it. I was amazed and pleased that I didn't have to use the 9" Mustang II brakes. I got the universal shock brackets and 65-66 Mustang spring pads from Currie, too, and welded them on. An 8" is the same design as a 9" so it's easier to work on(IMO) than an 8.8 and I can change the gear ratio quick and easy if I want to. I drag raced my 13 second Mustang for over 20 years and never broke the 8", I'm confident I won't break this one going to the transfer station, the hardware store, and Home Depot.

I sniff fuel for a living. Don't judge me!
You just jinxed yourself. It's gonna break on the way back from Home Depot now.

You're probably right. I said last week that I was looking forward to an early spring, the weather this morning said 6-10" from Monday into Tuesday. Hopefully it'll last long enough for me to decide if I'm happy with the gear ratio. I'm running a C4 so I went with 3.00's due to not having overdrive. I'm not good at leaving well enough alone so I'll probably change it to something else just because.

Walt:

I'm following your progress - I'm working with an 8" for the front axle of my tandem - Fred Hone mounted his OD unit off the front of the differential (17" long/6" diameter) without failing the differential, so I figure a "throw over" transfer case, should be OK.

You don't mean the 8" will be driving the front wheels, right? You'd need to find reverse cut gears or you'll be driving the coast side.

Forward rear axle would be 8"; Aft rear axle will be Dana 35 HP.

Nice professional looking job, that's a little more involved than my project.
