Here's where I'm at. They don't sell brackets for my Chevy. The rumor a coil spring bracket (with a cut-out to clear rivet) works may be a myth, because I'm 90-10 certain the bolt pattern on my truck 5.3/10" is right. The forward most hole is center the shackle bracket. A SWB 2WD GMC is in the same boat (leaf springs). Unless you're lucky enough to find the right OEM brackets (I'm looking), the coil spring brackets can be used with say a 5/8" extension and a new hole added.
Be great to receive some confirmation, but it's the outer bracket that has me stumped at the moment. Why would they be different for my application? That's why I'm asking for confirmation on the placement of the rear hole on the frame. For what it's worth, the bolt pattern appears to be 5" on most trucks.
Appreciate all input, pretty please thanks. And no, I'm not drilling through the frame
