I'm guessing that as it is likely a cdn. production truck the "Ingersoll" steering gearbox could have possibly been made in Ingersoll ont "?!?" I just swapped the one on my 58 last weekend for a slightly better one. Both were Ingersoll's & yes you have to take the shaft out right up to the steering wheel. I can't remember if on a stock truck you can slip it out of the column without completely removing the outer column I couldn't get enough room cuz of the exh. pipe coming off of my small block's manifold, so I hadta take the outer column off. , but this gave me a chance to re bushing my auto shifter (57 ford car) and tighten up the shifting mechanisim.
