It is official, rods are toast. Now rebuilders

Now on another topic, which came up after reading a few of your replies about Warranties? I never even considered trying to buy another engine, but searching online there seems to be a Engine Locator service that has reman engines? with 7 year warranty? wow. and for much less than a rebuild (if I have a shop rebuild).

So now my question is, there seems to be 2 different types of slant 6 225 engines dependingon year. 1966 and older has a different engine part number, than 1967 and newer. the 67 and newer says it has a 2.157 crank hub?

will either engine fit or do i need to limit myself to the 1966 version?
Also I like the fact that these reman engines require me to reuse valve cover, chain cover, oil pan. So that is stuff I can do and feel like I am "rebuilding" it. Right?

Also this would assume that I need to get a hoist and stand (looks like I can borrow one from the forum member) .
