I'm expecting big improvements but haven't taken it out for a long test drive yet. There's a river calling me...
|This bracket is oriented correctly|
I got an e-mail from Jim at Orbital Machine Works after he looked at this post noting I'd installed the lower mounts on opposite sides from their intent. The gussets on the lower mount should be nearly vertical rather than nearly horizontal. Switching plates from side to side didn't change the location of the lower shock attach bolt but DID resolve the slight clearance problem I'd had and got the gussets oriented to oppose the shock stress as designed. Big thanks to Jim for his helpful response!
