Re: Ryan Overdrive
Grant - I don't have information on the Ryan Overdrive. However, would it be possible to put the truck on jacks, remove the spark plugs, and put in high gear with the over-drive in overdrive. Then start counting revolutions of the engine crank and the rear wheels. I would think with a little mathmatics you could calculate the overdrive ratio.
Just an idea. Of course if someone could forward you the information from a manual or brochure; that would be best.

PS. Sorry Grant, I wasn't fast enough. Steve had the info.
