Hi Guys, I asked this over on the Nailhead section, too. My speedometer in my 63 Riv reads fast by about 20 %. I pulled the old speedometer driven gear out and it had an 18 tooth gear in it. I pulled the driven gears out of two Dynaflows that I have at home and found a 19 tooth gear in one and a 20 tooth gear in the other. Both the 18 and 19 tooth gears were kind of a cream/white color, the 20 tooth gear was red. I installed the 19 tooth gear as it was the same color and got a slight improvement, but still reading fast. I was concerned that if I install the red gear that it may not be compatable with my speedometer drive gear in the transmission. Any thoughts on that? Also, I was wondering f anyone has a 21 or 22 tooth driven speedometer gear for a Dynaflow that they would like to sell? Any input would be appreciated! Thanks, Tim McCluskey:Comp:
