3/4 ton rear question

I been searching for ring & pinion gears for my 69 C20 but havent had any luck. It doesnt appear to be a dana rear, the cover is round and has a 10 bolt cover. Anyone know where i can get 3.73's, id also like to convert to 5x5 axles, just cant find any info on these 3/4 ton rears. Thanks Chad

Re: 3/4 ton rear question

If your cover is round with 10 bolts, you most likely have an Eaton H052.
Available gear ratios were 4.10, 4.57, 5.13 and 6.17(?)
3.90 was available aftermarket.
A very desirable option in these rear ends was the NoSpin, or Detroit Locker traction aid.

Pretty tough to find replacement gears or parts for the Eaton's. I finally replaced the whole rear end with an Eaton no spin. Dana's seem to be the one most want.
