Sup guys
Alright I got an unorthodox underdrive crank pulley.
What belt sizes do I use now? And if only it was that simple, but also, im running without P/S, so im thinking that theres only going to be a short belt going from the crank pulley to the water pump and thats it then the other belt for the alternator and all that. Can anyone inform me of the sizes or part numbers for this.

Thanks in advance
