Would love to help you guys on this one, but I bought the GM skidplate last year after waiting for years for somebody to make one. Only thing that sucks is it has to be removed for every oil change, since there's no hole for draining oil! Oh well....looks good, and is very sturdy. Good luck. I'm definitely interested in a rear diff skid, since Calmini is never going to make theirs. Let me know if anyone wants to make that one.
