I think I'll just order that kit from Amazon. I came across this
mount online last night and I think I'm going to attempt to mount a flashlight with a red LED to it on the non drive side and I don't think the bolt is long enough to secure a rack and fender at the same time. Got to do some quick measurements before placing the order for the light and a mount for it to attach to that 'stub', as I'm pretty sure my LBS can get me the Origin-8 thingy.
