355 Gear conversion/New tires

[smoloney]

Had my conversion done for several years now, standard 3 on the tree. Is there away to adjust/correct the speedometer?

Thanks Steve

The easy way is a speedometer ratio adapter. Just type "speedometer ratio adapter" into your favorite search engine.

Go to TCI "speedometer gear calculator" to get the correct speedo drive/driven gear formula and eliminate any ratio corrector. Your speedo is reading too slow now so what we do now is to use a gps to find the PERCENT difference between indicated speed and actual speed and then use a set of gears that will read that percent faster.

I found one I just need to confirm the threads on the end of the cable that attach it to the transmission do you know if they are 7/8" x 18 thread ? Thanks! Steve
