Rollbar Stays / Cross Member

[brainbug007]

Thats good info, thanks alot. I've got a proper roll hoop from ash and it's just the stays and the bit that goes across for the seat belts to mount on that I need. Would the 19mm stuff the rear end is made out of be ok the for stays? Also do you think i'll need the bar that goes across the roll hoop if I'm planning on using the seat belts out the donor and making the additional back stays with the 3mm triangle plate for the belts to mount to?
