Anyway, going to try to replace this and see what happens.
is this:

(btw this appears to be a pretty hard to find size)
the correct replacement for my current:
Yes I measured the spindle length with calipers, it's 107mm. English threading, right?
Weird how it has a piece that snugs against the outside of the BB shell on the drive side, but sits inside the shell on the non-drive side. Is that normal for these vintage bikes?
Thanks for any help.
I just did a bottom bracket and yes you are on the correct glide path. A small hint though: I got frisky and just had to have an aluminum non drive side piece. No plastic for me! Mistake…..the aluminum one had deeper threads than plastic one. As I ran it in the spindle started to bind. Ugh. So…get the new BB but if you get binding head to the local bike shop or recycle shop and get a less deep NDS
