Harness anchor point

[will_08]

Evening

ive got some seats and harness's for a bargain off Ebay, not collected them yet, but the shoulder straps look fairly long. (infact they drape on the floor in the pic)

might not come to this, but would it be acceptable to have the shoulder anchor points on the bottom back chassis rail, instead of the roll bar? like the sides are if you get what i mean

any help would be much appreciated

Cheers Will
