Don't know if it is all there but would be a start.
Unless you really know what you are getting, could get costly real fast between buying, shipping and repairs to buy a dedicated tool to do the babbitt in the rods. The less costly tools were setup to do only one size and might have been ok in the day to get by with.
Hopefully you understand that there is more to the job then just pouring some hot metal in a mold. There are lots of videos on You-Tube that can help, along with practice.
If you are going to do the job, you will also need a way to check the babbitt temperature. You will need a Pyrometer that reads up to about 1000 deg. f with probe for checking temp of babbitt.
Also don't forget the tinning butter and a tool to check the rods for straightness.
You will be working with metal that is in the 700-800+ deg F range and is not something to take lightly.
I would suggest posting an ad in the classifieds in parts wanted, T, A and early V8. There would be more then one maker, so do some research.
You could do a google search; "Fordbarn; rod boring" for example. Not trying to scare you off from trying, just offering a bit of info.
