Where does this spacer fit?

Hello all,
Can we play a game of “what the hell is this and where does it go”"?

I have this funny spacer in a box of stuff related to the servo and master cylinder.

Can’t figure out from my hundreds of photos where it goes.

Anyone has a clue?

The more I look at it, the more familiar it becomes. Will sleep on it (not literally…).

Eric: Is the mystery part rubber? And what year XJ6 do you have, as it could be significant if it’s from your vehicle.


A wild guess from afar. the grommet for the firewall. The rod from the pedal to the MC travels through it???


It seems to be made of a light alloy, possibly aluminum.


how about size, diameter? Is this center hole threaded? Again, what size?

I’d see this thing on a longish rod, shaft, lightly fixing or clamping a breakable (plastic?) item via the shaft, meant for being fixed just finger tight.

Does this help?

Good luck

2cm diameter, not threaded. Bizarre.
