viper 99 cc

I picked this up and didn't notice you have to bolt it down from the bottom. Is this a common setup? The bolt pattern is a lot smaller than what it my bike is setup for. only one bolt works. I am just going to make some slots for it. I could just make a plate, it would be more work. Anyone have any idea on the best cheapest way to go? Thanks for any help.
