This hump thing ain't going too smoothly. Prior to getting back into the hump mode; I hooked up the speedometer with a cable I already had and it looks like it will work. Can't wait to find out! Do to my dissatisfaction with the original hump mods; I'm exploring an alternative solution. I knew that saving that old transmission hump for 20 to 30 years would pay off! Still adding trans fluid but close to first gallon completed. Hump thing still bugging me so might just work on locating seats on new floor while I think more about the hump. Opportunities!
