I was thinking the same thing on the Jetskihaven plate,it will need to be drilled in a different pattern of course, the kicker is the Yami cases hit on the second boss where the engine bedplate bolts up right in front of the starter,on the stock plates they just drill a hole and let it stick through the bedplate no big deal,I am not sure you could do that on the aluminum plate without severely weakening it,the plate would also have to be extended on the front about an 3/4 to 1 inch to be able to mount it up.I am thinking if you cut the boss on the bottom case to about half the thickness it is now that it may clear the bedplate with maybe a shaved head bolt of course,I will have to look and see if I have a trashed case here somewhere to play with.If I can come up with a modded stock plate for a pattern we could send it to John and I am sure he would have some of them made up if the interest is there.
