Hey Matt, this might sound a little redneck but here goes, could you grind the sight bracket down enough to make up for the 1-1 1/2 and use a little shorter bolt??? Not the kind of stuff that I would normally suggest but it might get you to shooting for a while and save you some cash for the time being. If there is enough stock on the bracket I try to grind it as even as possible. I have had a similar problem with a RH bow and I made a shim to put behind the sight bracket and used longer bolts....Just an idea to get you out of a bind maybe...
