Much difference between these aside from the obvious? I'm going to want to mount them to the rear upper original seat belt mounting point (one each side) and therefore there'd be no benefit in 4 point over 3 right?
if thats how you want to mount them then 3 point definately better. No real difference between the two unless the fastener can accommodate a 5th mounting
3 point for that sort of mounting, thats where I had my 3 points bolted up to, I bought some 4 points in the end and mounted them where the standard belts mount on the floor
Where do people mount the the side mounts (nearest the handbrake) ? If its in the bolt that hold the original sealtbelt clip to the seat what size is this bolt please so I can go out now and buy a eyelet bolt?
