Can any of the parts guys tell me if a '84 F350,351W,4spd trans is a NP435? I'm hoping for a direct swap for my T18 in my '70 F250CS,360FE. My T18 is worn out at the shifter pivot area. Are the speedo hookups,bolt patterns,input/outputs the same? OR....Should I put a new top&stick in theT18? Any guesses on parts cost? I can't be the first guy with a wallowed-out stick pivot. TEACH ME,OBI-WAN!!
