Anyone familar with the center console cassette holder system?

[Porsche-O-Phile]

My '74 came with this option apparently (stack of "c-box" cassette holders manufactured by Fischer). Problem is I'm not 100% certain I have all the pieces to the stack. There's a bracket that slides into the top of the center console "cubby" attached by two screws and with two tabs that sit in small slots in the top of the cubby to prevent it from sliding out. The cassette boxes then interlock and slide into that.

Problem is there's nothing holding the back of the cassette boxes flush/vertical so they tend to get out-of-line - the lower ones will push into the cubby in the center console further than the ones at the top, since the console is deeper towards the bottom and the boxes interlock by sliding in from the rear. I noticed there are two small slots in the bottom of the center console similar to the ones at the top, also two small screw holes so I'm wondering if there's a lower guide piece that's supposed to be there.

PET doesn't show anything, just the P/N for the boxes themselves (911.645.226.00)

Yeah, yeah I know. I'm probably obsessing about something that's outdated/irrelevant today anyway but I'd like to at least understand this system for authenticity purposes.

What's a cassette?

Take that crap out and put it in storage for Hershey.

Cool, thanks - I'd appreciate it. I'd like to have this system set up as a bit of testimony to the age/heritage of the car.

the piece that you are missing is the plastic piece about 3" long on the right side, I think mine goes on the left side.

Porsche-o, my hat is off to you. Let me know if you're still stuck. I'll take mine apart if I need to.
