Going through Hurst Shifters today and comparing some un-identified rods with known rods and wanting an opinion or confirmation of what I believe I have. Picture of rods shows starting with top rod and every other rod (positions 1 top,3&5going down)compared with other set I have (positions 2,4&6). 1,3,5 are the original rods off my 396 car. 2,4&6 rods are another identical length and shape set which I believe are BB rods, too. The second set has more threaded area on each rod and the shifter is dated 3-69. My car is a 12B 68, shifter is dated 6-68. The length of rods are 1-2=14 15/16 in.3-4=17 11/16in. rev=9 1/8in. (give or take 1/16in on each). Shifters show back nut I believe (according to AIM)is unique to BB shifters. Closest shifter in pic is off my car, 2nd in background is 3-69 shifter. Anyone want to comment based on their car or experience if I am right and have 2 sets of BB shifter/rods? Oh yea, I did extensive search on the site before posting and could not find an answer. Only marking on rods is a "D".
