Early A body K frame.

Will a 65 Dart k frame fit in my 71 Demon?

Normally people swap in the other direction... Idler arm is $$$, steering linkage obsolete...

I located a 65 Parts Car, and my demon doesnt have a k frame.

It won't fit, too narrow, need a 67-76 A-body krfame, pref 68 up to get away from the single post idler arm.

=Daty

The 67 unit is a one year only design. Stud mounted idler arm. 68 -72 were the same except that the idler arm fit into a pocket, allowing a firmer support to resist deflection. In 1973 the K frames were redesigned using a different sway bar AND to improve the motor mount retention. The "spool" design was superior to the biscuit/pad design. Oh, the 73-76 models also benefitted from a better center link and tie rod design. The short answer though, is NO. The 63-66 A body had a K frame unique to themselves. The 67-76 K member will fit any 67-76 A body though.

Thanks Guys! I still plan on getting the Parts car for some other goodies.

63-66 k frames are all the same for /6 of V8 it is the motor mounts that are different

This is how ALL of our cars should have been. It sure would have saved the factory money AND all of us time and effort today. The mounts are different for slant six and V8 cars anyways......
