Hi, was wondering if the upper frame for the asian fit jawbone and regular one are the same? i.e can you attach an asian fit jaw onto a regular jawbone upper? Why im asking is because I have some plans to do this for the BMX chrome jawbone(they don't come in asian fit right?), and before I spend big money would like to know if it is even possible! For me the problem with normal jawbones is that the bottom part of the frame touches my cheeks, sigh... Thanks!
