Harness advice - shoulder mountings not 15/6" what to use?
Hi Guys,
A recently acquired an excellent pair of Radical harnesses to use in my Striker - the only problem is the mounting points on the shoulder straps.
The holes appear to be M8 or 5/8" which means the standard 5/16" bolts are way to big.
Currently, I only have a three point mount behind the seats, a loop arrangement welded to the top chassis rail.
My question is: what bolts to use for mounting, and am i safe to drill through the rail, or is it better to have a flat bracket welded onto the rail
to mount too? or maybe an L shape bracket bolted to the existing loop bracket? I'm sue pics will help, so i'll try and get some
uploaded!
Anyone go experience of using this style of harness in a 7?

Ideally you want a 10.9 or equivelant bolt
If you decide to mount through the rail you really need to weld in a solid boss of decent size first.
By the way 5/8" and 8mm are not close in size, do you mean 5/16" ?
Cheers

Standard seatbelt/harness fittings are 7/16"UNF, and need to be at least grade 8.8 or equivalent.
