Question:
Good evening I have a question about your Universal fifth wheel rail mount kit. There are no directions in the kit just parts list. There are two longer carriage bolts and two tubes. I’m assuming they are spacers, but I was wondering if they sit in between the bottom of the bed and on top of the mounting bracket. It looks like such a huge gap with the spacer on. I just wanna make sure that I am doing this properly.

Hey Nick welcome back! Sorry the Curt item # C16101 only came with a parts list, that's not helpful at all. I found some instructions for you that will answer your install questions in greater detail. The full kits like the Curt item # C16200 come with installation instructions for multiple models of vehicles. I have attached them below.
What kind of truck are you trying to install them on?
