Don't look though your inventory for real angle - the tank stiffeners are not made from angle stock. They are just aluminum sheet (maybe 25 thousandths) cut into strips 1.5 inches wide, punched, notched and bent 90* by Vans at the factory. If I recall correctly, they are 3 or 4 feet long and you cut each one up into 4 or 5 stiffeners. At least this is how they are for the 7 and I think the 8 should be exactly the same.
