47-55.1 Eliminate draft tube options

[TX3100Guy]

Lee, thanks for the info.

This morning I used the depth measuring section of my digital calipers to get the internal measurement of the block opening to the cam gear and oil pump drive. I wouldn't call this 100% precise, but its pretty darn close.





as best I can tell, the shaft portion that goes to the oil pump drive slot on both the new distributor and the OEM one I bought at the swap meet are 1/4 inch too short.

I have calls into my engine builder to confirm the cam gear version and any change to the oil pump itself. I also have a call into the magneto folks (Joe Hunt) to get them to give me some measurements on what I sent them.
