Yes,
I use Rod-holders. These are plastice with foam inserts, that you attach to a boat. Each rack has about four slots that will hold the bolts or anythig else you can insert onto each slot. I also don't see why you couldn't use a wooden cue-stick holder and just turn it on it's side. ....
By the way, I mounted mine on the sidewall as opposed to the door. I had plenty of room. ....
Be Safe !!!
