i took this to mean: is there a hole in the K and frame that match each other and you could use a tool/pin for alignment in the assembly process. which there is not.
the datum pickups are the LCA pin holes and the front strut rod mount. besides the mount holes, there's only the sway bar holes and drain holes-- neither of which are remotely close to any measurement in the diagram in post #42 or in my 69 manual (23-148 fig. 3) [confirmed on a 67 K and a 73~76 K].
which, understandable. but those don't really help in putting it together in that you can only measure it once assembled.
