62 k-frame is either a slant 6 k or a V8 k.
One year only V8 k-frame in 62 used for both small block poly 318 or big block.
Metal mount on k-frame is the same for sb and bb, engine mount is different.
I pulled the poly out of my 62 and kept the 2 piece metal mounts, but I don't believe I kept the rubber mounts.
I know the rubber mounts are same up to 64.
