Google speedometer gear calculator. It's more in depth than you might think. Tire size, drive ratios, rpm at cruising speed, all that takes place here.

Assuming it's a '68 based on your screen name. 1965 and down is a different chart.

That is a very small diameter tire for any C-body. Specs from several tire brands at Tire Rack show it has about the same revs/mile as the old E78-14 size. Might need to get into an A-body listing in a Chrysler FSM to find the stated speedo gear combinations, I suspect. Or maybe a B-body listing. 802-806 revs/mile. By comparison, an H78-14 ('66 Newport 4-dr w/factory a/c) was 753 revs/mile.

Hope this might help,

Figure out what gear you need and then place a Parts wanted ad here for a used one. Brewer Performance and Mega Parts USA are a couple vendors that sell new ones.

What year is your transmission? It makes a difference.

I believe it's a 1975 transmission. It has a off white Speedo gear in it
