Alright guys. In a bit of a dilemma. I have just purchased a 94 c3500 crew cab dually. Turns out this truck was originally 454 not 350 as it is now. Add to that my nv4500 decided it doesn't want syncros anymore. Have yet to find a show that actually wants to mess with rebuilding it and can't locate a used replacement anywhere copie. My questions are can I use a 96 or newer nv4500 with my year? I've seen there are differences for the 4x4 but not the base trans. Also will this work with the 454 or am I gonna have to replace it again? I've had mopars all my life so kinda outta my comfort zone here. Thanks in advance for any advice
