Dana 60 posi rear
 

Dana 60 rear with factory posi unit and 4.10 gear, drum to drum. It measures approx. 54" from each end of the axle tubes. Not sure what it came out of, but doesn't appear to have been narrowed. I was going to put it in a 71 Formula but changed directions. Prefer pick-up...it is HEAVY! $1000

Sounds like a B body rear at that width . It should be 60" overall outside........You might want to pull an axle to see if it's a 35 spline axle . ....'67 & '68's had 28 or 29 splines ,later ones had the 35 spline axles.
