As for the ac/ it looks pretty similar for those two years, I'll take some pics and post em later...

So you guys think I can swap the tranny??? On one hand I'd be losing my freshly rebuilt 727 but also wouldn't mind rebuilding the 518 and swapping it if it'll give me better mpg's.
What exactly would I have to do? Will it bolt directly to the flexplate or will I need an adapter??
