I bought a HD Dana 70 out of a dually pick up truck and the WMS was way too wide. I ended up trading it for a cab and chassis dually 14 bolt. That probably didn't answer your question. Id assume that dana 70s are just like 14 bolts and the WMS depends on what it came out of. Especially seeing as how both rears I mentioned came from under chevy trucks. They have truck duallys, cab and chassis dduallys, van, and truck. And I think even two or four wheel drive might be different. The WMS and drum sizes are different amongst all of them from what I have seen. But I dam sure am not an expert in rearends.

Dually axles (non cab and chassis) are usually 70" plus for the WMS-WMS and way too wide for a car.
I've put a standard width Sterling (65.5 WMS-WMS) in an box Imp and if fit like a glove.
Without knowing which D70 you have it's hard to say, but if it's in the 64-67 inch range it should fit nicely.
When junkyard shopping for a full floater, generally cab and chassis will be the narrowest (although sometimes like in the case of the Sterling the C&C is the same as a single wheel), followed by the single wheel, then the vans generally have a wider rear than the trucks, then lastly the duallys will be the widest.

The guy I traded the rear to claims that all FF 14 bolt rears are the same length overall. It's just the WMS that is different.

Not quite the C&C and SRW are the same housing and axle shafts, just different hubs. The Van axle is a different housing and axle shaft length, but uses the SRW hubs, and then the dually uses it's own housing and axle shaft length with the same hubs as the C&C version.

No idea what all those abreviations mean LOL. I will look at the axle width before I buy it.

C&C is cab and chassis. SRW is single rear wheel, sometimes people refer to those as standard width
WMS is wheel mounting surface, it is what you are supposed to measure the distance of to get an axles width. When people try to measure from backing plate to backing plate, it can often be inaccurate due to different width hubs on different axles.

He claimed that all the 14 corporate FF axles are interchangeable. What you are claiming counterdicts that. But you might be right. Im sure you speak from experience? IDK? Very informative if so. That's useful information if validated. Because it disproves my previous understanding. Is the same truth similar with Danas? I am not attempting to call you wrong. It's just that he seemed a reputable source based solely on his collection of a hundred 8 lug rearends and him being 70 years old. But we all know that doesn't mean anything. I had an old guy tell me to fill my tires with water when I first started derbing.

This one is out of a dually so I'm guessing it'd be way too wide?

www.pirate4x4.com/tech/billavista/14b_bible/ That link has more info on the 14 bolt than you will ever want to know. As far as the Dana's I've only messed the SRW version so I'm unsure about the other versions. I would assume just by looking the dually version has a wider housing and shafts. The 14 bolt and Sterling are both that way.

Honestly when looking up info for any of the full floaters, I suggest snooping around the offroad sites. Those guys have been playing with full floaters before the aftermarket even started making parts for any of them. I know derby guys thumb their nose at the offroad guys axle advice mainly due to the offroad community liking the 8.8, but the truck 31 spline 8.8 is a completely different piece of equipment compared to the car 8.8, and the truck 10 bolt is a pile of garbage compared to the old iron 10 bolt.

The 14 bolt I got is not posi .. with that being said best to weld spider gears or just buy posi spool?

Welding 14 bolt spider gears isnt like welding a normal axle like a 10 bolt. You have to disassemble the carrier to access the spider gears. You can buy a mini spool for $125-150 or a full spool for $300. Some guys weld them, but it's a little bit of a time consuming process if you've never done one before.
