I'm missing the 7mm thrust washer for the tach gear. I bought a 1/4in .030in thrust washer and a 5/16in .030in. Of course the bearing shop(nor anywhere else I called) seemed to stock metric or 9/32(closest to 7mm), so I figured I can use the 5/16 one or open up the 1/4 a little to fit. Since I've never seen the original thrust washer I have a couple of questions. Not sure what the thickness is supposed to be, so not sure if 0.030 is good enough. Also the ones I bought are chromium steel and am unsure what the original material is or if that'll affect anything.
