I've confirmed that the Victory-specific mounting bracket doesn't work for the Cross Roads. The Honda one works well, and I was able to make it work without needing the spacers mention above (though I'm currently using just a U-bolt; clamp is on order). The parts you want are:
JCB03-HBK01P - Polished Mounting Bracket kit for Honda Cruisers
HCL-01 - Universal Handlebar Clamp
You can use a U-bolt, but the clamp is a polished piece, and the U-bolt won't be too long and look goofy.
