Is this a 12 bolt?
This rear end has been on the FB marketplace for about a week and I'm wondering if it's a suitable swap for my 6-lug Dana 44. I've been researching options to convert my Dana to 5 lug but just haven't found a good option. I can swap axle shafts on a 12 lug pretty easy and if it's the wider rear end that eliminates the need for wheel spacers.
I want to get some measurements off it and compare to my dana to see how they compare. Does this look like a 12 bolt? The seller says it's from a 1/2 ton Chevy or GMC but doesn't know what year.
