I'm looking for some guidance on removing the saddlebag spools on my 2019 Chieftain. I bought an aftermarket tour pack and I need to install spool bushings before mounting it on the bike. I don't have quick release saddlebags so the spools are secured using a hex head bolt (not an allen head bolt) and they are so freakin' tight that they won't budge. I'm afraid to really bear down on them. Has anyone else seen this? Should I just put all my weight into it until they loosen? Thanks in advance.
