Glad to see the repop of the 65 speedometer gear. I have a 3.91 geared 65 Automatic car, does any have a chart for the tooth count? Planning to run 275-60/15 tires on it.

brewers can tell you ....

Here 'tis. Also wants an adapter.

you need a 21 tooth pinion and a .80 ratio reducer and most likely a different speedo cable. don't confuse this with the '66 and up speedo pinions.

not sure if the antique tires sizes compared to P numbers will be a problem or not?. there was another chart (MP?) that used diameters. Way back I used it & it was dead on.

Thanks.
