Shift Kit

Alright so I pulled the valve body out of my donnor trans that I thought was a 74, turns out it seems to be a 76, or atleast the VB is due to the 6 passages on it (so the TF-2 instructions say). I'm hoping to use this VB in my 72 trans so I can keep driving the car and pull the VB and replace it with this one in one fell swoop. I'm guessing it will.
I haven't lost any balls (yet lol) but some fell out into my sink and I have no idea where they go lol
Also I opened a side port to clean out the fluid and some stuff fell out, think I got it in right but idk, here's a pic, springs are back where they go and the pistons are correctly put in but that gap seems weird.


I also have no idea where this goes either, accidentally let it fall out without seeing where it went, some help would be great where this stuff goes back haha

So far so good though!

Here's a few pics
