Aaron:
This is how I installed my 5 point system, not sure if it is the best but here goes.
On the lap and the submarine belts, I went thru the floor of the body. Under the floor I used 3" dia flat washers. The shoulder straps go thru the cockpit back wall to the down tube bracket for the roll bar and mount in the locking bolt for the tube. That braket is mounted to the frame.
Some may say that the floor mount is not safe, but I figure the thickness of that area, almost 3/8" in some areas with the large flat washers, it should be strong enough. I hope! Another way would be to use a steel plate under the body maybe.
Not sure if this helps but that is what I did. Ofcourse there are no instructions in the manual abaout sealt belt installation practices are there.
Roscoe, what did you do? I should have talked to you first, just kidding. You know I appreciated your advice in my build.
