Eaton HO52 fill plug needed - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm hoping someone out there replaced their rear end and still has their old Eaton HO52 10 bolt diff cover with the fill plug. I've tried every auto and plumbing supply store in Northern Virginia with no luck. The plug appears to be 1-inx20. I am really close to modifying my diff cover if I can't find a used plug. Please let me know if you have any suggestions-- the PO managed to get by with a load of Permetex around the broken plug. My '69 C20 Camper Special thanks you!

Looks like 344829 is the number you seek.

Might want to post a WTB over in the classified section as well.

Tim,

That part number was the hint that I needed. I should have started on the boards before I drove all over Northern Virginia. Thanks again!

I may have one, I'll check tomorrow. Just shut the shop down for the night. I think mine is a 12 bolt though, but I will check and let you know.
