I just got my 127 box home and discovered that it did not come with mounting hardware or instructions. The box seemed to be factory sealed. Do I need to purchase thes items seperately?

should have had j bolts for install included. call your place of purchase

Yeah that's not right, they must have forgot to put the hardware package in the box. My 127 came with a baggie with j-bolts, nuts, washers, a rubber pad, and instructions. Oh and little plastic discs that I can't figure out what they're for.

The little plastic discs are for holding the J-bolts in place to prevent it from slipping out when installing and adjusting. Also act as sort of like a washer.
