what I'm hoping is that my '60 K is the same as the '64 as there are many parts available. I'll do some measuring and see what I come up with. Thanks everyone for your input so far...
From input on this site, 60-73 A body frame rails are the same. If the width of 60-61 frame rails is the same as 62-66
then a 62-66 K member should be the same. As I measured on the 62-65 B body K members they are 3" wider.
67-76 A body K members are wider than the earlier years, as by then, Chrysler had already decided to put big blocks
in A body vehicles.
