early a k frame spacers?

I am building a 64 Big Block Dart and plan on doing the same thing.

What I have found is that if you use the later disc brake spindle (F body type) it is 3/8" longer that the A body disc brake set up. In addition Howe makes a 1/2" longer upper ball joint. These are popular with the circle track guys.

So in theory if you used the above parts you could space out the K member 7/8" and your geometry should be ok. I have run this by Bill who makes the alterkation setup and he said that it should work ok. By the way he is the one that told me about the Howe ball joint.

Good luck,
Mike
