Slant 6 with 200r4?

Over on slantsix.org .They are working on a group buy right now and has all the info.
Do a search. A guy over there that goes by Dart270 put a A500 in his 68 Dart. They say the 200R4 is much easier and less cost.

Dart270 is my brother in law . I know that he has the wilcap adapter but as of this July he hasn't had the time to do the install .
