Well no response via email for Bettany but I don't know if the email address is correct as I pulled it up off the internet. If anyone has an email they know to be correct please post. I may case of I just simply have to call

As for the overdrive 5th this actually leaves me an option; my local track is a medium to low speed track but the other tracks I might go to are medium to high speed tracks. With a 4.38 rear end and short Hoosier tires 8000 rpms in 4th is 112.

One of the alternatives is to find a 4.625 rear gear, that combined with 20.6" tall tire would allow me to use 3-5th and still have a 115 mph to speed for the long tracks.

It still pains me that I have a full set of mid close and two sets of ultra close main shaft gears for the 56 series 4 speed. Not to mentioned two damaged mid close cluster gears. If cluster gears could be had I'd be able to build at least two more gearboxes, this would be a 15 year supply for me. Wa wa wa.
