I have a 1968 Chrysler newport custom with 2bbl 383 w/o a/c. It only has the two belts in front. I went to buy the belts but some say accessory others say fan and alternator which I know I need but the other one I am not sure. Every place has ones that are different lengths listed for certain belts. Can someone lead me to pick the right belts please. Also my fuel gauge isn't working and I replaced the tank and the sending unit, any suggestions on where to go from there and last my speedometer is way off, i have 225 70 14 on the car.

 

If you have the old belts ? Look for the numbers on the belt. Or take the old belt down to the auto part store and have them measure it.. Then record the numbers..
On the fuel gauge make sure the sender is grounded

 

Thanks probably going to have to rebuild my carburetor too it sat a long time

 

The sender is grounded so and the wires are all in good shape i will be cleaning the contacts even those they are good but maybe the fuel gauge is bad.
