9" Backing Plates Gm Drums

[Boz]

Does anyone know who makes a backing plate for a 9" that allows you to use G Body drums? I had set set about 6 years ago but can't remember who made them. Thanks

Moser and Dutchman both make 9in pockets with bolt patterns for stock brakes from other makes. However Im not sure if either of them make the Gbody style plate with the screw in spring anchor.
