Hi Bob, luckily it just bolts in!. The pitman arm on the 67s is a one year only expensive part to replace. Also the 73 up a body k member has the desirable spool mounts that make mounting the engine easy and cheap. Also I am going to run the disc brakes from the 73 up era which requires replacing the spindles, and upgrading to the more desirable larger balljoint upper control arms.
In the end you get the best version of what mother mopar came up with for the a bodies, after everything was standardized (easier parts availability)
