Looking for a speedo gear for either 3.91's or 3.55's.Going in a 904 tranny if it matters.

Thanks.

You have to choose one gear or the other, then cross-reference it to the actual tire diameter to determine the speedo gear you need. 727 and 904 from 1966 through the mid or later '70's take the same long shaft gear.

I have some for sale here and a chart is included in the ad:

[FOR SALE] - 727/904/833 speedometer pinions & related parts


I beat BadSport by .01! :poke::)

I have 3.90 gears but my tire diameter will be taller than stock so it will probably be more like a 3.55 actual ratio.
Either one will be close enough for gov't work.

pm sent.
