small block k member differences

the frame width is different Early A to 67 and newer A body. bound to be other issues too.

What car are you trying to put a 360 into.

there are conversion mounts for 67 and newer SB v8 into 67 and newer slant 6 K frame.

I seem to recall that Early A used the same K for slants and V8s but that needs to be verified
