Keep the head rests, odds of being rear-ended are greater than that of a
rollover.
If I'm not mistaken, grade 8 bolts are less prone to stretch, ie more
brittle. In an accident, I think you'd want the bolts to stretch, not snap.
I'd go with the regular grade bolts.
Large thick washers designed for seat belt mounting work great on the
underside of the car. You want to distribute the stress over as large an
area as possible. From new some of the better roll bars had flat plate
steel that went on the underside to distribute the stress. Also I'd use
nylock nuts so that they don't vibrate themselves loose.

Rollbar is installed with large Grade 8 Bolts and Nuts and backed up with
several large Fender Washers on the under side. Any other recommended way of
securing the underside to the car. Welding is not an option at this point,
and I need to be able to get the top up and down.

I can remove the headrests from the seat and gain that inch back but I
think Ill make the tradeoff and keep the headrest on.
