thank you for the reply...my gosh i have posted my results on so many boards with zero feedback. I like the fit of the boot of my supreme80's, and would absolutely consider a new chasis if they are mounted to the outside...got any pics? I would be worried about the extra drill holes too, but if they are indeed on the outside it may work....any extra info would be greatly appreciated...I have spent so much money on past skates and this current conversion...in fact i am using an old pair of mission proto vi's with tape around the ankle of my left boot where the boot is torn. Desperate here, I am. please respond!
