A came across your YouTube channel a few months ago and having been watching your videos.  Your knowledge of cars is impressive but what I find most impressive is your honesty and how you've made a successful career sharing your knowledge/experience with the rest of the world.  

I've never heard you talk about antique vehicles so if this is not the proper place for questions with cars that old I completely understand, but I'll ask just in case.

I have a 1929 Model A Ford that I've bought a new distributor for.   It came with a 2 piece distributor shaft.  The problem I have is the new upper shaft will not drop into the original lower shaft, which sits down in the engine.  It appears that the new upper shaft has a slighter wider notch that will not sit down into the lower shaft notch.  The new distributor also came with a new lower shaft but I guess I was hoping the notches would be the same and I could just lower the new shaft notch into the original lower shaft notch but it's not precisely the same dimensions to work.  Am I going to have to disassemble the engine to replace that lower shaft?   Any information or advice you can give would be much appreciated.  If not, I completely understand on such an old vehicle.   Keep up the great work, love what you do!  🙂
