5 or 6 Point Belts on an ERA?

Five points are fine. Without attaching anything, layout the harness with you in the seat to check the lengths you'll need.

Drill a hole through the floor which is clear of the X-member and under the approximate middle of you seat. Get a grade 8 bolt as big as the hole in the belt mounting tab (usually about 1/2"), and a 4" square, 1/8" thick steel flat gusset plate. Drill same as floor. Use grade 8 nut and washer. Install the bolt with the head 'up'. Install with gusset under floor and space the tab off the floor with a washer. Through bolt the assembly.

Don't attach the belt to the seat frame.

Used a 1/2 in. Grade 8 (5 is OK) bolt down through the floor with a fender type (large OD) washer to spread the load. Installed the seat-belt tab centered between the seat tracks and pointing forward to a rear-most position so the ERA floormat would fit. The floormats go in the trailer for track events.
