We at Rocket Restorations just got three "lunch pail" cables with 70-71 dates. Pictured; top is used original 71 Hemi Cuda 20" length trace of mint green paint, second down new Hemi 20" mint green with 2180 date, third 22" red ink spot 1229 date, bottom 30" no color 2?60 date
I don't know application on the last two but I hope the picture will help out in identifing assembly line vs. later replacement cables. Does anybody know the application on the 22" and the 30" cable?
