Ok you knowlwdgeable people. What speedometer cable gear do I use for my charger. ??? I have a 354 Dana and am putting 275 60 15s on the back. Thanks in advance for the help. ::)
The book says a 3.54 car uses a red 36 tooth gear with 235/60 R-15 tires. A 4.10 car uses a white 42 tooth gear with 235/ 60 R-15's. But with your 275's it might feel, and be more like a 3.23 car which uses a 32 tooth gear. :icon_smile_big:
I think Year One has a guide... at least on catalog, not sure about on line guide
Here you go, chart with gear ratio and tire diameter, part #'s, etc.:

A 3.54 gear with a 28" tire calls for a 33 tooth pinion.
The color is yellow and the current P/N is 52068155.
33 TOOTH IS THE CORRECT ONE. THANKS FOR YOUR HELP.
