I seemed to have developed a "flat" spot in my steering when turning left on my 56 Victoria. I have looked at Mac's and T-Bird products and they have parts to rebuild the box, but they say either two tooth or three tooth? How can I tell without taking the box apart? I would like to order the parts before I rip it all apart. Also does anyone (or theses companies) sell a "rebuild kit" as per say, instead of ordering individual parts?  Thanks in advance for any help! 

I love the smell of burning rubber in the morning!
