crank pulley
 

Hello out there, I am new to the site. I have a 1988 GMC Suburban 2500 with a 6.2 engine. I am having a terrible time finding a replacement crankshaft pulley. It is a three shiv "v" belt with a rubber inner ring and a bearing. Dealer wants over three hundred, got to be something better. Any ideas or leads? Thanks, K.O.
