There's a chart in the AIM that shows which gear is required.

Thanks Guys, Yes even thank you to you too Mike I'm just looking for the stock gear as it was dead on with my tires (which I believe are stock height). I'll comb through the AIM to see what I can see.

I called Bowtie Overdrives to get the new speedo gears for my '79 that I am converting to a 700R4 transmission. My rear end is a 3:55, and my rear tires are 28" diameter, size 275/60/15.

Bowtie said my drive gear is 15 teeth and driven gear is 38 teeth.
