I only know of two K9 frames. The Daytec version, which I own and they don't bolt up to, and the BD version, which I own and they don't bolt up to. Yes cutting the eyelets is a possibility and would help move the shock away from the support bracket and I am going to show that in the next day or so. My first two thoughts we're to cut the eyelets and cut a small portion of the shock body away as I think that might be enough but, as I've stated before, making modifications to a part that has been designed to perform a certain way is never a good idea and will almost certainly end bad eventually. As it is majority of the soft tail frames are at a disadvantage out of the gate because the shoulder bolts are too small and break too often.I was thinking not trimming the body but "adjusting the eyelets" might be an option. There's a pretty thick plastic washer protruding (with steel sleeve) What if a thinner nylon bushing were used and the extra distance were added back to the outside so that the bolt is still the same length.
Also, if there are different frames amoungst the K-9's do we have anyway to tell which is which (by vin maybe) so that we can test all versions.
