Because i'm in a $hitty mood this morning i'll gladly throw a wrench in you plan...
Byeai and Yami-Rider are building ride plates for Trendsetterz Chan's. Steve was very reluctant to send replacement plates and the assumption was he wouldn't send them because he knew his plates wouldn't necessarily fit on his own hulls. Of course it could've been that he was lazy ("busy") and didn't want send them, because reasons.
I'll try and add a glimmer of hope to the painful dark and dismal future of your personal water craft experience...
Your best bet is to have a ride plate made very thick. The rationale being that if its thick on the "outside" then you have plenty of material you can grind off to get proper fitment against your ski without making the new plate too thin.
I don't know how you guys manage to drill new holes for those plates.
Good luck.
