Doesn't look like you can shave the housing like 14FF though or can you? Probably wont need to with what your going to use it for.
it looks like you can, and also the lower holes are through holes.
you can probably shave an inch off and plate it pretty safely.

These rears the 70HD were found in 30 series trucks also...from 73-89 2 and 4x4 and about any gm chassis camper..If the camper is 10 lug most likely it a 70HD They are out there , just have to look..
Oh yea did you know they make a DANA 80 HD in the new F350 trucks..

I picked this up a couple of years ago. It's a "new old stock" 70HD and the application was a late 70's Dodge motohome. It's never been installed in a vehicle. I don't have the hubs . . . I'm assuming they were 10-lugs. I wonder if a regular 14-bolt or Dana 70 hub would fit?

My 97 Dodge Cummins 2500 4x4 (and everyone elses) has a dana 70 and the complete authority for those vehicles, the Dana 70 & Dana 80 is tdr.com (turbo diesel registry) The rear end itself is a nice heavy duty piece and I doubt you will hurt it. The extra webbing on that one is cool and unique. The powerloc LS is lacking and most recomend a Detroit in those rear ends if you want real traction.
The LS has been the topic of many, many post. Personally I have never had any problems with mine, currently at 325,000 miles...but I would say the vast majority of owners don't care for the powerloc LS. As noted they are rebuildable....but even in "like new" condition they are prone to slippage at the worst time and act more like an open diff than an LS.
Congrates on the find...stick a locker in it and your done.
On the that 70HD, I would say that 94-97 Dodge 2500, 8800 GVW rear hubs would fit. If they don't fit, the 3500 series Dodge hubs should. I'm not sure about the years but Dodge used the D70 on the 3500 series for a awhile, before moving to the Dana 80.

the LS is really what im looking for, because i didnt want to shell out 600+ for a detroit. im going to really try to have less than 300 bucks in this by the time im done.
this axle is way beef but its gonna be awesome when i build a 70 front for my dually.

the housing in post #36 doesn't look like it has the same beefy webbing as the OP's housing, but can't really tell from the angle of those pics...are they different castings? and the OP's rear end is an 8 lug where as tvguy says in post 36 he thinks his uses 10 lug hubs...if i find a 10 lug d70hd or d80hd can it just be swapped over to 8 lug hubs & if so what would the replacement 8 lug hubs come off of?
thats what i would like to know. i want to try to pick up another one now that i know how to find em.
