Well that escalated quickly.

I bought my '66 and managed to drive it 10 miles home with a badly slipping clutch. Thinking I'll just replace the clutch and enjoy the Barracuda the way it is, I pulled the tranny, found the back freeze plugs leaking, and two two others on the side with crud seeping out. Long story short, became a three year mechanical restoration resulting in pulled and overhauled engine, new suspension from and rear, engine bay sanded and repainted, new interior .... you get the idea.
