jerico transmission overdrive gear set

Description

jerico transmission overdrive gear set. These gear will replace your third gear in the transmission and give you an overdrive of .78
You then flip the 3-4 shifter lever and use 1st,2nd,4th and then 3rd which is overdrive. These came with my jerico for Bonneville
and I never changed it from the .84 overdrive it originally had. They have sat on the shelf ,but have never been used..
