    I need some help I have a 1985 Chevy silverado and basically run it to run like a 1999 0r 2000 chevy silverado. Someone told me the cheapest easiest way to do this instead of trying to swap everything ove to just take the body off the 1985 and put in on a 99 or 00 is this even possible or could you point me to someone who would have some advice on this. thanks

    How did you get the cruise control cable off of the throttle body?

    i did this swap to and got a 99 6.0 for my 99 sierra to replace the 5.3 .. turns out you need a 01 or newer or that spacer that you can remove to run the 4l60e is built into your crank and its you cant remove it... so your stuck swaping the 4l80e into it....

    Contact Circle-D and tell them your setup and they can build you a custom convertor to work with your early 6L/60e combination. Going to 80e would be good insurance, too.
