I'm only running an alt. pulley and a crank pulley. The alt. brackets that I have, possition the alt. pulley closer to the balancer/motor. Is there a stock serpentine pulley that I can buy that will work?

 

No water pump drive?

Measure teh length of the required belt with a string. Take the measurement to your local industrial power transmission supplier. They'll have whatever length you need. Poly V belts are manufactured in various cross sections in about 20mm increments. Gates, Dodge, Goodyear, and Browning should have a standard size that is close enough.

 

I see how confusing my initial post was. Sorry about that. I'm not worried about a belt. I need to either space the alt out from the motor almost 2" or move the crank pulley back 2". Which would require me to buy a different crank pully.

The pulleys are not lining up.
