I have the wide pulleys available and you can order online from the website and see what i have been doing in my absence. The address is fifthaveinternetgarage.com
Go to the parts counter and you will find what you need.
The pulley diameter is important. the 2.5 diameter helps increase the alternator output at idle and low speeds. Our engines do not idle near as fast as the modern engines...
It often makes the difference between bright headlights and dim headlights....
Thanks Randy
