I have the QR sissy bar on my Thunderbird and want to mount saddlebags using easy brackets.
Do the bags end up outside of the shock absorbers, so any bags with rigid flat backs will fit?
I can't quite be sure from the photos.
I have the QD backrest and EZs. I don't believe a flat backed bag will clear the shock. The SlimBags I got have a cutout for the shock. If you took a 1/4 inch piece of plexiglass and cut it to fit between the EZ and bag as a spacer, it would clear the shock. Come to think of it you might be able to get slightly longer bolts with the EZs and put some washers behind the EZ mounting spindles. The EZ bolts are special for the triumph backrest so EZ should be able to tell you what size bolts to get to accommodate a spacer.
The reason I went with the dimensions of the 112+2 saddlebag is it fits between the shock and the rear turn signals. You just have to be careful where you attach the EZ Bracket to the saddlebag.
The below images show the placement of the bracket on the bag and the space between the bag and the rear turn signals. There is roughly between 1/8" to 1/4" between the shock and the bag.
