I'm looking for the tension straps for a tilite back for an 18" wide TR. I only need parts 1 and 2 in this picture http://estore.tilite.com/ecommerce/P...08/5-5.1.3.pdf

I'd be open to non tilite brands as I'm on a tight budget (saving up for an adi back).
I'm also open to trades or partial trades as I have some tilite hardware and accessories (used breathable back, wheel locks, side guards, ect.)
