Ken: I believe the bars you want to use are 7/8", not 3/4". That being the case, you can use Jackal risers and clamp, as I do on my 2003 California Stone Touring model. Harper's and others will be happy to provide a set. You need buy only the risers and clamp. The nuts, rubber spacers and metal cups all are interchangeable. I never liked the OEM Stone or EV "Beach Bars" and converting to the Jackal clamps gives the rider a wide option of bars to use. You know, I'm sure, that all the switches and controls are 7/8" i.d on the fat bars of those Stones and EVs, just the ends of the bars are reduced to 7/8" to accomplish that. It's a very easy conversion with which I am very satisfied.
