I just got Harley saddle bags for my wifes Deluxe, the parts list says there is a bottom bracket for them but every one I have ever seen on the road doesnt have them on. Can you only use the bolts that mount through the bag or is the bracket necessary.
You can get by without them. Just don't load full of weights. They are not big enough to hold that much anyway.
If you install after market full exhaust you will have to leave the bracket off the right side. Bracket only fits with stock exhaust.
I've been running my Deluxe bags for 3 years now without the lower brackets with no problems at all. Makes it real easy to take them on & off for cleanning or the "cleaner" look.
