I also have a 59 and the oil canister was mounted between the carb and the firewall(after my dad rebuilt the engine in the 80s). I moved it to in front of the carb because of the cast-in "lugs" on the intake manifold. My shop manual doesn't show a good piture of the proper location but I can't think of a reason for the casting on the manifold other than the oil filter canister. Some one with an assembly manual my have better info. The lines are plenty long enough to mount it either place.

I know you believe you understand what you think I said, but I'm not sure that you realize that what you heard is not what I meant!
