Yea man, thanks for the suggestion. Tried first with a hand drill, no use. Ended up getting a mate to sort em out for me. He said it was the toughest steel he's ever come across!
The plan is to pick up a Chrome Porter bag when I get a few bob, it'll be bungees till then so we'll see how it handles
You drilled out the mounting tabs then? Nice work. The real handling test is when it's fully loaded. :)
