How should I replumb this?

Always have the end in mind. Make sure everything is glued before that final end piece lol.

False alarm. I had those pieces dry-fit, not glued.

Even though the primer may be purple, I always have a sharpie pen and mark both sides of the joint with a dot or an X to tell me it was glued. That way, you can review all after and ensure each joint is glued.
Also once the union is hand tight, make a mark on the collar and the mating piece. So if it leaks, you can see how much you have additionally turned to stop the leak. Then mark it again as the final position. So if you take it off later, you know where you have to tighten back to.
Just little things I picked up on DYI projects.

Thanks. I have it all back together. I seem to have an air leak but have everything lathered in shaving cream and cannot figure out where it is.

So, I measured 10 times and cut once on this project. It all worked out with just enough space.

I woke up this morning to no bubbles, so something must have settled in overnight.

Here is the final photo...

THANK YOU for the advice...
