Not to high-jack this thread but....
My ole 24 leaks like a siv and occasionaly pops out of gear. I researched rebuilding it then read that the 205 will bolt right in it's place.
Keep'un an eye on CraigsList I found a 205 from a 1976 F250 for $100. I plan on rebuilding it an installing this spring.
Just another option for this thread.
