RR had their structural engineer guy whip up an attachment system for the shoulder belts back in 1998, but it doesn't actually mention bolt size! (See the two links below for details). I think the plans call for 3/16 bolts holding the seat belts, and I get the impression from the links below that he intended the shoulder belts to be bolted with .25" bolts, but if the scale of the drawing means anything, it's clearly 3/16" or even less. I'm not saying I agree, or that it's right, just throwing it out there as the "official" word from RR, for whatever that's worth. http://home.hiwaay.net/~langford/seat1.jpg http://home.hiwaay.net/~langford/seat2.jpg The above links are accessible from http://home.hiwaay.net/~langford/misc.html also, about 2/3 of the way down. Scott, did that article appear in an old Newsletter or something? If so, aim me towards it and I'll check it out.
