Thanks so much to you and the OP (CajunCountry), I got stuck when I pulled out both bolts on one side to install my back rest. I came on here and found exactly what I needed. I first used your advice to push the metal at the back of the fender up a little and pushed the front bolt in and then the back bolt (also had to push that metal piece up).i got frustrated with the saddle bag bolts on the boulevard too..so came in to look up some info. i tried different suggestions i seen here sitting on bike, etc, but this worked for me. put front bolts on first...the back i spent over an hour trying to get the bolt in. i finally just pulled up on rear fender lightly with my hand and the bolt went in like a knife through butter. took it out and tried again before i signed up and posted. might save someone an hour of frustration. l
The other side, I did it as CajunCountry said with the front bolt first and then the back bolt, one at a time.
