Konica Lens 28mm f3.5 EE loose aperture level, small parts

Hello,
I came across this lens (bought 'as-is' so not sending it back).

Discovered that aperture lever is loose, and and when moving aperture rink there seems to be some 'grinding' but not positive aperture clicks.

I decided to take a look inside, took off the metal ring, and then these 6 miniature pieces came out.
Seems like 2 springs, 2 metal balls, and 2 metal pins.

Where they are from, and how deeply would need to go disassembling it (I assume from the bottom) to get to the place where I can install them back?

The springs and balls are most likely from the aperture ring detent mechanism. Taking the lens apart until you can remove the aperture ring should reveal where they should go. Or, maybe not - advice worth price charged.

Following @Nicholas Lindan -> here is another lens showing the aperture ring locking mechanism with spring and a ball:
