You'll also find that rear axle seals, bearings, etc. are primarily Ford parts. The Columbia rear end is a nice option. Is it the version that has a speedo cable that goes all the way back to the rear axle? If you haven't already done so, you should get a copy of the chassis manual for a 1937 Zephyr, you'll find it invaluable. Check the vendors listed on this site. </div></div> It looks like the speedometer drive gear is right behind the trans on the torque tube. It's gone, but that looks like where it use to be. Sorry it took so long to answer the question CBoz.
