Flash Bracket + SC29??

I had this flash bracket for a while now, its gathering dust because I can't mount the SC29 with flash on it.
It's got a hotshoe tightening mount which accepts all hotshoe flashes but discriminates the 1/4" screw mount that the SC29 has...
Anyone know any solution on how to mount the flash with SC29 attached?
