Need Help Adjusting Bindings

Just bought a pair of 2004 Blindside Stomp bindings on eBay for cheap and need to adjust the straps for my wide feet. Problem is getting the bolts back in is a nightmare with the one piece plastice support that circles the binding. If you ever tried to adjust bindings, I'm sure you know what I mean. Any hints or tips on how to do this before I throw them out the window. Any idea how much a shop would charge. Is it better to get them wet so the straps stretch a bit more. Anyway, any help is appreciated.

Not wet, but warm. Heat them up a little & they will stretch out. Threading the screws through the plate, throught the plastic piece, throught the overlay to the nut is a bitch. It always has been on every binding. The only way I found is to have a screwdriver in the slots ready to go & push as hard as you can hoping to get a thread caught & able to tighten. Sucks but thats all you get...

vice grips or those quick clamps or whatever they're called. Now, I have no idea how blindside bindings are constructed so I can't really help you with that. I took apart my LF ultras and these would have helped. I abandoned the project b/c it was turning into a major pain in the ass. But if you put the clamps on, then take out the screws, it should help. just an idea.
