727 speedometer gear

When I do the calculating I show you need a 35 tooth (orange) gear. I used a measurement of 26.57" for your 245/60-15 tire. Plus it is best to have your speedometer to read a little fast than a little slow for obvious reasons. When you find one I would be interested in your 29 tooth gear. It is the one I need for my '74 D200.
