Can anybody tell me the WMS measurements on the 3" drum single wheel Dana 70? Mine bit it yesterday and I'm just gonna swap in a FF14 bolt. I need to figure out if I need one from a truck or a wider one from a van.

 

~66 inches. WMS to WMS.
VAN SRW axles are usually narrower.

Mark.

 

Thanks for the reply. GM truck FF14 bolts are 67.5 and vans are 70 (1973-87ish). My friends and I have always swapped in van rears to get away from the width difference that GM had in the trucks between front and rear. I know my ratios won't match but I'm holding out for a 4.10 rear. I can always regear the front a few paychecks from now.
