    I don't see why one from a NBS truck wouldn't work work just fine. You may have to work on the hole where it passes through the firewall just a little but that should be easy enough.

    Not to sure on your 1974 truck but on my 1992 I used the 1999 throttle cable. I just had to shape the hole going through the fire wall so cable would fit.

    I used the 1992 lower radiator hose and I am using my original radiator. Truck came with a 5.7.

    I needed to redo the cable itself once upon a time and just used some home depot 3/16" cable...same thing as the stock one.

    I used a 2002 cable on my 92. Same with the radiator hoses, all designed for the 2002.
