Help finding correct V-Belt

[7Dcuda]

I just bought a 70 Cuda w/ a 440.  It has manual steering and originally had A/C but doesn't now.  My problem is this....with no P/S pump or A/C compressor, the fan belt goes over nothing but the pulley on the water pump and the crank, hence no belt tension adjustment capability.   The belt thats on now is way too loose and I have experimented with numerous different belts of varying length and width combinations and cannot find a belt that is not either too loose or too tight.  Anyone else had this problem?  I know I could go with a different pulley size or install an idler pulley but looking for help for the simple fix of just finding a proper length belt.......anyone???

alt, crank, and water pump pulley. The alt is where you adjust the tention

IF this belt went around the alternator, sure.

you need to locate the correct pulley & brackets to run without  the AC  first

These will work just fine, and it is hard to find them any cheaper. You could own these as quick as you push buy now

Thanks guys.  I understand all that, but as stated in my original post, was looking for taking the easy route and just finding a belt that worked.  Thought somebody else may have went through the same scenario and found a belt that works.

the problem is with no adjustment any belt you can install will be too loose

  All belts stretch that is why they have adjustment. Get the correct brackets/pulleys and use the alternator for what it was designed for.
