Re: Front Differential Question

...and are 8-lug w/bigger brakes.Or,was there a 1/2t version?I never heard the HD designate until coming on here.
I`m not sure about the transition year on the front axles.But,you can visually I.D. the axles.
Tim`s advise will do the trick.I assume it`s the original axle to the truck?

GM C30s could still be converted to 4wd by NAPCO in these series.They used a Spicer axle that was the same old design from the`50s,like the HO52 Corporate.I had a`71 Custom/30 NAPCO years ago.
