yeah they made 2 LH brackets in 68: for the 273/318 and the new 340 for the one (LH) side. the right side is the same across the board. the 3445 part number is the only new one made for the 340's changed motor mount boss location. The only difference may be the number of mount holes (3-4) which is not a deal breaker. So maybe the 67 is a 1 year design but not in function but more in appearance? Thats a new one for me. Happy hunting!
