We're putting a 56 cab on an 89 4x4 full size chassis, using the original 56 gauges and the tank and sender from the 89...or at least I hope so. What kind of problems will we run into? Can these be made to work? Any thoughts/suggestions appreciated before the smoke starts rolling. Thanks, Steve

what engine? gas gauge won't work, or at least won't read right - other gauges should - let us all know how you deal w/ mounting the cab and front sheet metal!

Cab is a 4400 series and already mounted on the 89 chassis w a 350/5spd. Moved the firewall back a bit for the the HEI. Cab sits well on the frame, 33's fill the wheel openings. Bummer about the gas gauge though because the original cluster is in great shape. Guess I'll have to keep track of miles.

I got a feeling that somebody with a box of resistors couls make your gas guage work. It's an electrical circuit and can be manipulated, all it is (I think) is a ammeter with an F at one end and an E at the other. Don't give up, find an engineer.

Jim Bow, thanks, yeah I thought so too but I'm not sure what the resistance is on either the old gauges or the new sender. Guess I could get the 89's stats at a Chevy dealer...the 56 is a little long in the tooth for finding that stuff. O well, guess work and smoke...hope it ain't smoking in the gas tank though that could get ugly.

The 89 runs from 0-90 ohms. Dunno about the 56...
Hold the sender in your hand, wired and grounded to the truck , and move arm up and down slowly, see how guage follows. Safe easy test.
