I'd give V&H a call. They'd probably send you one at little or no charge that fits exactly the way it's supposed to. Best to loosen everything up...fit everything together loosely...and tighten everything up in it's correct position. Otherwise you wind up with one out of place thing stressing another until something gives...especially on a rubber mounted engine's exh. syst'm...knowhutImean !?!
I've never worked with the folks at V&H on things like this. But I have with the folks at Kerker-Supertrapp and on several different occasions over the years they've sent me bits & pieces FREE for USED systems that were missing those things...rather than charging me their minimum $25** fee. In fact, just last year they sent me some mounting hardware for a '75 Honda 750 basketcase I finally got around to rebuilding & reconditioning after being "stashed" in my folks barn/garage

for several years.
Worst case scenerio...you waste (?) a few minutes of your life on the phone you'll never get back...
