Outer primary help please!
I found this on ebay that absolutely suits my needs (long story short, mine is chrome & I want to chop it in half to run an open primary while keeping the electric leg without blowing my entire build budget) but I'm not 100% sure it's going to work.
It looks to me like the jackshaft bearing support is shorter than it should be for an '80s motor, but I'm really not knowledgeable enough to be able to tell & my googling over the last week is failing. Badly.
This is what I currently have......
Aaaand, this is what I'm looking at.....
The reason for my skepticism being that I've already bought what I REALLY wanted: a NOS Paughco tin primary for the electric shovel, and the damn jackshaft bottoms out in the bearing, before the case is fully seated 🤬
Could anyone tell me, with absolute certainty, whether the Ebay case will actually work for me, or not?

- Don't cut the cover down as much as I did here. You want the end of the jack shaft covered, not open as my temporary setup was here.
- Remove the rest of the chrome with a sander, etc....
