turn signal switch

Have any of you guys had problems with aftermarket "repair kits"? My 67 barracuda has issues with the signal lite switch and i would like to replace it with a whole new assembly if i could. I see that Herbs parts lists one. mopar performance list one for 70 -77. when did the lane change function show up on our mopes? would be good to have . I think some of the later ones had the hazard (4 way) lite switch on the column ,so this would not work for mine.
