I need pics of a '91 crewcab ('73-'87 body style) engine pulley setup. Mine looks like an '86 setup w/the serp/v-blet setup. My '90 sub has a full serpbelt.Anyone know if this is correct for the '91 Crewcab or has it been hacked up? The crewcab has a v-belt driven alt. on the pass side & the air cond. compressor on the driver side, just the opposite of my sub.
