I have a set of "stove pipe" commandos and they have the three individual "tabs" and I thought that they were 66. It would make more sense if mine were 65's and his were 66's as it has the same long wire harness brackets as a 67.
It doesn't make sense that they went from the long bracket to the three short "tabs" for 66, and then the long bracket for 67. It makes more sense that the short 'tabs' are from 65, the long bracket is 66.
