Agreed - the fixings weren't that great, but to be fair it was very cheap... I didn't use the bolts it came with either - I used some stainless ones from my box of usefull bits. Any chance of a pic to see what yous looks like ?
There you go. Handy box if I'm honest, I only use the CRF for commuting to work so leave it on all the time, surprising how much you can fit in it.
