I have 1946 Hudson truck with 3 speed. I want to convert to overdrive. Is the OD unit used the R9B-1 or R10? Can anyone tell me where to acquire one with all of the associated bits? Also interested in 308 engine. Thank you in advance, Kevin Morrow

    My understanding is that they are the same '41 to 'mid '52. I don't any longer have one with all of the accessories or peripherals, but I might be able to come close. They are heavy to ship, 144 lbs, if I remember right, but it can be done.

    Hi Kevin what worked for me years ago for my 1947 Hudson pick-up was a 1956 308 with 3 speed and overdrive along with a Ford 9 inch 3:50 ratio rear end. Able to keep up with traffic and still keep it mostly Hudson parts.  The original 6 cyl had only 3 main brgs and was babbit bearings which now is nearly impossible to find a shop to do.

    James, where do you live. I am in Delaware. I would rather come pick up rather then ship.

    kmorrow, may I suggest that -- once you've determined exactly which overdrive you want -- you start a new discussion entitled "overdrive wanted"  and put it in the "Parts & Pieces" section (under "Classifieds" in the menu to left).  State exactly what you want, and your location.  

    Currently, your wish for an overdrive is part of a discussion called "1946 Hudson "Bigboy" truck.  There might be someone with a transmission to sell, but he won't pay much attention to your posting because it isn't obvious from the title that you're looking for a transmission.  

    Just a suggestion.
