I am working on a '55 now and it has a 4 spd Muncie. The speedo gear is gone from the trans and I want to replace it. Does anyone know of any p/n's or starting point for me? I know I will have to play around with a few different ones due to tire size. Can I go through GM for these parts? I thought I would ask before I went into the local dealer.

Thanks. :dunno: :dunno: :dunno:

A good "old timer" parts man at a dealership should be able to set you up. If you get some guy that just keeps asking you what the application is, just run away.

If you give me your rearend ratio, and your rear tire dia. I have a formula that will give you the drive and driven gears for the trans...Crash

Andrew/Crash....Thanks for the help. The rear axle ratio is 3.73 and the rear tire is 8" wide approx. (235/70/15). I believe we are going to a higher gear soon (numerically lower), however, I would like to get the speedo repaired right for him now. Thanks again.
