so when i picked up my bike (1999 shadow vt1100t), I got a windshield with it from the p.o. My problem is i'm having trouble mounting the windshield, I've never had one to put one on before, I can't seem to get the fork brackets to line up correctly with the windshield. It always ends up off kilter and the slide pin doesn't fit correctly in. Any suggestions would be helpful, Thanks Guys and Gals
