Did you manage to figure this out? I need to get around to modding mine but might go with an LS-56 if the LS-32 doesn't fit. I wonder if Smoke re-used the original shaft...
EDIT: For anyone who comes this way, OP states they used an LS-33 on their twitter not an LS-32, I guess they're not...
Oh wow that's cool, shame there wasn't a high res magneto artwork to finish it!
I almost got this poster but the seller said he didn't check his stock or something and so didn't have it :/
