I have been looking for the same thing??? It looks like I am going to have to look up a "tinner" friend to design /make me one so it is done right. If you found one, please post it. I hate to take advantage of friendships if I don't have to.
I have been thinking about the ALR. Legion post #1 in Omaha has an ALR and their web site says they welcome other post's riders. The post I have belonged to for 40 years doesn't have an ALR. Thanks. I thought I would want to be prepared before talking to them about joining their ALR.
