II has some on their site... though I think they are all just stock stiffener plates from Cummins with hole drilled in them for the 14mm mainstuds to go through. Add a shimm between the plate and main cap and Walla! a $450+ girdle that Cummins sells for $55 minus the holes LOL
I'm just going on what the pics look like... if I'm wrong, tell me.
