Thank you 3B and Hotrod Lincoln, and Merry Christmas!

As I feared, it sounds like time to pull the transmission to inspect the clutch and pull the windshield to get it re-sealed. Having laid under the truck looking at the large (and heavy) transmission and related mechanisms for a dump bed, I am not inclined to take this on in the field. So I will probably drive the truck to an experienced mechanic's shop and have a new clutch installed to be done with it. I am not prepared to remove the windshield on my own either (and would hate to break it without knowing if a replacement is available). But I can try to seal the edges and now realize that I can check to see if the seal is leaking by covering it with PVC tape and then hoping for more rain to test it.

Thanks again for the advice. It is greatly appreciated. I still think this project will end up as a good ranch truck with the advantages of lower licensing and insurance costs and being exempt from most state inspections.
