Found out I'm getting 3 point seatbelts for Christmas.

What size bolt should I get for the shoulder part up by the door in the corner?

There should allready be a nut welded in place. Don't remeber the correct size, but get the right size and get the bolt in grade 8 material.

The threaded weld nut in the corner is 7/16" fine thread. I used shoulder bolts for the installation so that the belt ends can swivel.

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs. Last edited by Andy4639; 12-07-2008 at 11:01 AM.
