AZ WTB Differential Plug and Posi Tag

[Sandemonium]

Does anyone know where to buy a differential plug with a posi tag like the one pictured below for a 12 bolt coil spring rear end?

I have looked on eBay and can't get a clear answer if the ones that are for sale are 1/2" NPT.

Thank you.

Any other vendors make this part?

I recently purchased a repo tag off ebay for my 12 bolt rear end under my 69 GMC K10. The were 2 sizes of tags one had a 1 inch hole and the one I bought had a 3/4 inch hole. If you look on ebay you can see the difference in the thickness of the tag where the plug fits through. I was luck enough to have the original pipe plug that has the groove for the tag to set in. I do not believe the plugs are reproduced. Take care , Bruce

At this point the important piece is the plug. I am very surprised a repop or another manufacturer doesn't make a 1/2" NPT plug with a shoulder or flange on it. Thanks for the insight on the tag.


Thank you,
