So I'm probably picking up a cheap worn CP plate from a friend to install a LS-56 stick into. The problem here is that both control panels come with the standard Sanwa mounting plates. I've found a lot of threads (mostly on AO) touching on this subject, but none come around to any really useful conclusions, and images posted are mostly dead at this point, so I'm sort of stumped about how to go about it.
From what I hear, Seimitsu's "VF" type plates should fit right over the Sanwa one allowing me to screw the LS-56 unto the bottom of the mount.

Obviously, that would result in a somewhat shorter shaft on a stick that's already pretty short to begin with, and I'm really not sure how much I'd like that. Of course, there's no way to say when I haven't tried it, but I'm not sure it's a risk worth taking? If there's a simple way I could mod the CP to better fit an LS-56 into it, I'm all ears. As I said, it's a worn CP, and I'm not shy of mutilating it. As far as I can tell (the plate is still in my friend's possesion) the sanwa mount isn't welded either.
Alternatively, I could just settle for an LS-32 stick, mount it the same way, and invest in a shaft extender (which unfortunately doesn't work with LS-56 sticks).
Now, I already have an LS-32 that I use in a custom X360/PS3/PC stick, and I'm actually very happy with it, to an extend where I'd preferably never play shooters with anything less. The control is so much more precise, that I immediately perform better than I would with a JLF. However, from what I hear the LS-56 goes a step even further in that direction, and for this project I kinda don't feel like settling for the second best if I could potentially get the best. But then again, compared to a way too short LS-56, you could probably argue that LS-32 is still "the best".
What do you arcade nerds say? Any personal experiences in this matter? I guess there's a final option of going for an actual Seimitsu control panel, but those are both impossible to find, and ridiculously expensive once they do show up.
