Looking for U-Bolts for 8 3/4"

Howdy all, cosgig here! I'm looking for some U-Bolts for an 8 3/4" rear! I'd prefer the OE kind with the flatted top, used is fine but if anybody knows if they're available new, I would go that route as well! Must be the flatted kind if I'm ordering new though, I can get the round topped ones locally!! Any help here is much appreciated! Geof
