I put washers on my support arm bolts recently. Once the shells are in the full upright position, there is little to no pressure on the support arms. However, you will need to support the weight of the shell in order to remove the bolt. I used a 2"4 and a floor jack to support the weight of the shell, and take the pressure off the bolt. Then, you can pull the bolts out easilly.
Also, I painted my washers before I put them on the bolts so they will match the paint on my TM.

Good luck!
