dipstick and tube

Here’s a pic of the fitting it’s called a weather head
it’s 5/16 inverted flare for the tube and the other side is 1/4” npt that screws into the pan sump. I’m not sure why you have something riveted to your pan because the original was a fitting spot weld to the pan from the inside and all that was visible from the outside of the pan was a threaded hole.
where is this pic?

the mount for the tube on the original pan that is still in the truck, looks just like the one on this other pan, that I'm wanting to put on the engine on the stand.
definitely no 90* Weatherhead fitting on either.

I'm hoping that the cracked tube doesn't render this whole pan, "junk". It's solid otherwise. I can weld in a patch in place of the dipstick tube that's there, easily enough.... or put another dipstick tube to that area.
The tube that sticks within the pan seems to "bell out" fatter than the tube that protrudes outside the pan.
It would have to be slid in from the inside, and would appear too long to be able to do so, so even if not "serviceable" over the parts counter, it would certainly make sense to have been a 2 pc assembly going down the line, back in the day.....
It would be nice, to be able to detach the part of the tube that protrudes outside the pan for assembly on the stand and also for installation into the truck, the way it just hangs out in the open as it does, I can see it getting in the way.
I'll TRY to get a couple of pix of what I am talking about, but cant promise anything.
