this may have been discussed before but i am wanting to know that if i was to buy some 25mm x 25mm x 3mm steel box section and made some brackets to weld on to the box section out of 3mm thick sheet, then used some more 3mm thick sheet to make strengthening plates to attack to the tunnel and the inner sill would this be ok and strong enough.
just wanting to know as its cheaper to buy all the steel and make it my self than to buy a ready designed weld in seat mount.
cheers James
