im having some trouble with the bom on this dana 60, i believe its a 58' and every bom guide ive seen usually starts in the 70's. ive used the "expert" on danas website and gotten nothing

its 30 spline, here are the numbers on the passenger side axle tube
date bom
2158b1 25861b

any help would be appreciated! thanks -jay

yea i got an unknown also.....all i have is the tag off of the diff cover...

all it says is :
3.54 (gears i know) (upsidedown triangle) F2UA CD
(upsidedown triangle) 605487-11


thanks

jay...are you sure you have the entire BOM? Usually they are 6 #s, some with a suffix.

ridefast....605487 = FORD Model 60 REAR 1992 - 1993.5 E-350 VAN SRW - FULL FLOAT - ABS
