Jegs, Summit Racing, etc... You are looking for a 7.625" (or 7.5") rear diff cover unless you have the larger 8.5" rear end.

Two days ago, I ordered Summit #8510400 cast aluminum differential bearing support and cover for my 1991 S10 Blazer 4wd which costs $150 and has a Summit logo. Trick Flow is the same cast aluminum bearing support and cover and is also available from Summit except it has the Trick Flow logo on it. The OEM 1991 S10 Blazer differential is a 10-bolt 7.500" liimted slip but the same cover also fits the 10-bolt 7.625" rear ends.
The Summit #730302 is a stamped steel chrome plated differential cover and only costs $25. The chrome plated version is a little too Bling-Bling for me.
Jegs has the same covers but are more expensive. Summit has Jegs beat on prices.
Summit and Jegs are the only two companies that I have found who offers a reasonably priced 7.500"/7.625" differential cover for a S10 Blazer.

Go with a cast aluminum one, every chrome one I''ve had leaks unless you sand down the back side and then they rust.

The 7.500"/7.625" 10-bolt Chevy locking type (G80) rear end is notoriously weak. You should consider purchasing the more expensive 356-T6 Summit/Trick Flow cast aluminum girdle-cover that includes load bolts to support the bearing caps. That girdle-cover will add considerable strength to the differential. If your engine has any serious power and you have tires with good bite, the 7.500"/7.625" 10-bolt rear end will not last, especially if your vehicle has a manual transmission. The power from the engine applied to the helical pinion gear tries to drive the differential out the back of the axle housing and can fracture the bearing supports. The aluminum girdle-cover adds support to the differential bearing caps.
The cast aluminum girdle-cover has a drain plug so you can easily change the rear end lubricant as recommended by GM. The aluminum cover also has a fill plug but the regular fill in the axle housing carrier is easier to use. The rear end with the aluminum girdle-ciover takes over two quarts of hypoid gear lubricant or until the lubricant begins to flow from the fill plug in the carrier of the axle housing. The bearing support load bolts torque at 5 lb. ft. or 60 inch pounds each and is secured with a jam nut. Use Loctite thread sealer on all the bolt and plug threads. Use Loctite N0.2 gasket sealer on the supplied gasket and the girdle - cover. Let the gasket and No. 2 sealer setup for ten minutes before installing the cover. Use no gasket sealer on the axle housing but be certain the axle housing sealing surface is clean and dry. The Loctite No.2 non-hardening gasket sealer is more suitable to non-rigid, vibrating assemblies. It is similar to asphalt but easily cleans up with rubbing alcohol. Loctite No.2 gasket sealer is resistant to gasoline, oils and solvents and will not squeeze out like RTV silicone sealer and will not get in the rear end. I use that sealer on engine assembly, water pumps, transmissions and rear ends.
