Help - ID the part

Came from the inside of the shift tunnel - up close to the tower base.
I suspect that it might be a guide grommet for the throttle rod.
Anyone know where it goes? I had the trans rebuilt last March, so the shop might have screwed up the re-install and broke/pushed it into the tunnel in the process.

FWIW, I'm getting an annoying rattle somewhere in the tunnel.

Referenced car is my 912E.
Thanks in advance, Bill K

Yep, three of these plastic pieces in the tunnel. Throttle bush. They get old and fall apart. One under the shifter, one under the e-brake and one near the shift coupling.

Thanks Mike. Would you believe I searched the Pelican parts catalog for those three words (throttle rod bushing) and got 56 pages of bushings from suspension to door locks ???

Thanks for the link. Would you know where they get installed. I looked in the tunnel for a likely hole to mount them and could not see anything obvious. Maybe I'm not looking at the right set of factory diagrams?

They are split along the side so they slide over the throttle rod. Grease them a bit.

Then, there are three metal tabs (1/2 by 2 inches), thin metal that's welded on one end and bent around. The bushings get captured by these metal tabs. Wriggle them into place and bent the metal around them.

They look like the metal tabs that hold the wiring harness in place along the edges of the engine bay.

You'll mostly be doing this blind, but it's not that bad.

Porsche could have certainly simplified things by making the tunnel bottom removable, like Corvair!

Thanks Mike.
Looking forward to having my hand look like a piece of hamburger meat
Doesn't look like there's a whole lot of room in there for my mitts and the shifter rod.
I hope it's worth the effort.
Right now the throttle rod is secured by a length of hose and a couple of zip ties along the fuel line.

At least I've got a good set of instructions - thanks.

It's well worth it. I did some work on my rod and failed to replace them, I ended up with a throttle that would stick. I tied a string to the pedal and grabbed it to pull the throttle back when needed The rod was mis-located and things were binding up because of that. It also vibrated against various things in there.

Replacing the bushings solved everything and gave me very smooth, clean throttle response. It's well worth it. Remove the shifter, ball cup socket, shift rod, and the e-brake assembly (at least move it out of the way). That gives you lots of access to everything in the tunnel. Bring a shop vac and some degreaser and clean in there as well.
