Re: sticker behind seat ?

I don't know if it is exactly 'common' but many trucks had the Detroit Lockers installed in the HO52 rear differentials of the C20's in these years. My '66 C20 has the Detroit Locker in it.

Re: sticker behind seat ?

does the "ks-10" stand for the gear ratio?, or what ratio would be in a 3/4 ton chev, I know of a 61, and a 65 that i can get, they are both ks-10

I can't swear to it sitting here at my computer at work, but I'm pretty sure my '65 C10 has that same decal.

HO52 and HO72 were models of the eaton axle. they both used a similar center section and parts can swap between them. The No spin was the posi option for those eatons.

Re: sticker behind seat ?

If you want more info, I posted some good links in this thread: http://67-72chevytrucks.com/vboard/s...ighlight=eaton

I believe the HO72 has an extra bolt hole on the front of the pumpkin.

HO52= 5200lb capacity 20 series, HO72= 7200lb capacity 30 series.1965 C 20's no spins were only available on 4.57 ratios. The No Spin is notorious for wiping out pinion shafts and bearings due to racheting up on sharp turns.
