Any Chevy 6 cyl wires will interchange..just pick a yr at the part house..same with a v-8..if you need longer wires just order BBC wires..

Any local parts store should be able to supply plug wires based on the info above. The engine was a standard 235 cubic inch that propelled many Chevy vehicles. If a local parts store can not find that simple info, find another parts store since they are not very well versed in vehicles or how to use their parts search function.
