does anyone know what size and where to get them,also the washers that fit on the top of the back ones.

Hi mate - do you mean for harnesses?

I got some 'eye' bolts from Rally Spares.

I believe as long as they are 8.8 hi-tensile any bolt should be ok - as long as it's substantial..

If your talking about the standard seat belt mounting bolts, (ala ford), they are m11, hard to get. best to visit your local scrappy, and don't forget the nuts, and washers. atb Chippy

they are for the 4 point harnesses

If you need eyebolts (for snap in belts) you need 7/16" UNF which come stamped 8.8 grade. If not anything similar size for the bolt it harnesses in 8.8
