Hi
@Bansheedave ,
Welcome to the group!
You got yourself a project right there.
If you have not found it yet we have a "Southbend Downloads" section here:
https://www.hobby-machinist.com/resources/categories/south-bend.34/
with nearly 500 documents it in.
There are many manuals and brochures that could show you what the original parts looked like, and maybe even some part numbers that could be cast into the replacement parts.
If you do not find anything there suitable for your lathe, post back with the "Catalog Number" and I'll see if I have anything at home.
