Early A mounts

Yes, it is the same K frame from 63 to 66. I have dropped slant sixes and V8 in 63 64 and 65 Valiant and Barracudas. I am not absolutely positively sure, but there may be a bit of a difference in the metal part of the mount in 63 then there is in the later years. I would check my 63 Valiant station wagon, but I have a 66 engine in it with 64 mounts on it. The K frame is the same though.
