Are the pass. side of the 67-69 a-bodies 318/340's brackets the same? The drivers side is different I see. What about the 65-66 273's what is the best brackets to use. I remember using the 273's but I had to switch them around somehow.
When using the right 273 mount on a 340 you cut 1 ear off the back of the mount and weld it to the front or just make a new ear t weld on. The left mount you just need a couple washers to space it from the ear.
