Bill, I enlarged the picture as best I could and "to me" it looks like your mirror is sort of "straight out" and I can't see the base.
Denny, underneath the cowling there is piece that the bolts that hold the mirrow go through. I've read about it in the past but haven't found that post yet. I even thought I printed it out as I know my memory is not as good as it once was.
Right now I can get under the dash and shoot a couple pics so that would be the best thing to do so everyone can see first hand. So, give me a day. WE've got to solve this problem for future posterity!!!
