I got dial up connection here so I try to look through Ricks catalog and such too.. buts its a slow process. I did see the camaro cable in one of there catalogs I did find that... you'll notice there longer than the original cable I posted a pic of but they will definately work.
Jerry.. yep the camaro and chevelle used the same buzzer as the truck around 68. Lots of truck parts were also used on cars... goes without saying that why so many trucks got stripped for parts. Chevelle and Camaro Canibals.
