Interestingly enough, I've found that many TH400 dip stick TUBES don't fit, even ones that are listed for the application. I at one time had a graveyard of tubes/sticks because of this.
If you need the tube and stick, this is the one that I've used on both TH400 & 4L80e, in both 68-72 A-bodies and 2nd gen F-bodies:

I believe I have used the ATI ones as well, but the TCi one was the first I found in my notes.
