Teddy and All: Going for top end, eh? Just kidding! Anyway, there is a nice chart in the 1958 Service Manual that addresses your question. For the 2.92(?):1 and the 2.93:1 axle ratios, the 17 tooth speedometer pinion is used. Color is red, although by now, it would probably be pretty faded. Surprisingly, this pinion is listed for ALL tire sizes, 7.50 x 14 to 9.50 x 14. This should be one of the easiest to find. Just to back up that statement, I have one if you want it! 300ly, Gil Cunningham In a message dated 12/20/2009 6:43:30 A.M.

I know someone out there has the answer thanks to all.
