Overdrive on a Dana 20
I have a 76 Scout with a 392, granny T19, Dana 20, 4.11 Dana 44's and 33x10.5 Buckshots. This low gearing works great on the trail but 3000rpm at 60mph really sucks the gas and sevearly limits my cruising speed.
Does any one know of a bolt on overdrive that I can use with a Dana 20? Do you know where to get one?
Am I correct in assuming I could probably do a direct bolt on replacement of my Dana 20 with a Dana 18 and use a Saturn overdrive from Advanced adapters?
I was hoping to spend less than $1000. Any help would be appreciated.
