Hey All: I just picked up a Cobra II headlight from Eastern Performance on eBay. I know some of you have this headlight on your Dyna. Which adaptor/mounting block did you use? I’d like to avoid taking off the old headlight until I have all needed parts in hand. My bike is a 2006 Street Bob FXDBI. The two choices of mounting blocks I’ve seen are: (1) ½” vertical offset, ¾” horizontal offset (2) ½” vertical offset, 1-1/2” horizontal offset Thanks much for any advise.
