Wow how many Mopars have you worked on... What you are saying is it was only in 1970 that they did the left & right lugs ?? If 70 was the last year for it and it wasn't pre 70...Wrong answer it was Pre 1973..1972 still had left & right lugs. And it went way back to the sixties and maybe but not sure into the fifties... Check in the manuals to check your failing memory..LOl...Bill:protest:
