Slant 6 Question

What is needed to use a 68 or newer engine in a 67 or older car/trans.
1) 68 or newer flexplate
2) adapter bushing to fit in the end of the crank. (I have these available)
3) for a 66 or older "A" body. A 66 or older oil pan and pickup tube (from the old engine)
4) Engine brackets and mounts from the old engine.
5) possible distributer and ign parts, depending if you are going to run points or electronic ign.

I'm putting a 71 A Body Scamp slant six into my 64 A Body Dart Slant six car.
