If you have 4 stays and they're long enough, this will probably be the most stable way to mount.
Dremel, hacksaw, grinder or big bolt croppers all work for trimming stays. Measure several times then cut as spares aren't always easy/cheap to come across. If you can leave a little extra length on them without interfering with the basket/bag I would, just to be on the safe side, but if you can't then get snipping!
