I'm putting a wheel together for my Triumph and I'm trying to figure out which brake plate is the right one. I have all the factory manuals (except '57...) and they just list the brake plate assembly as w1073- no mention of this w1057 or w1248. You can see the difference between the two, and I know I can make it work, but I'm just curious which one is correct for the pull through axle (pre '57?) and which is for the fixed axle? Any of you Triumph gurus care to clarify? If anyone is running one of these wheels, can you post a few close up pics? Thanks.
