Rear Diff. ?
WDM DC 1C30
2 47 9. S 322B
This is on an 81 F100, it came with a 300 IL6 & 3sp w/OD manual trans. But has been converted to a 302 & C6. Would like to replace rear gear & install a posi unit, but I do not know how many splines are on the axle. I do not want to replace the axles if I can avoid it.
Thanks in advance for any help.
I'm not 100 percent positive, but, I'd be willing to bet that you have 31 spline axles.
