I'm thinking of buying an old Kenworth as a toy hauler and am curious about the availability of parts. Its a 50s vintage vehicle, in great shape. has a reman 350 small cam cummins engine. Which I'm not sure is original equipment 5/4 transmissions. Its a W900 In any case I've picked the wrong vintage vehicle to try and maintain before and I'm curious about this one. How hard is the injection pump on this thing to get ahold of ? Any other trick parts ? Steering linkages ? Any ideas as to how tough it is to keep it running ?
