Funny!

I have plenty of room under the rear deck (or what's left of it) and the spare wheel well. In fact, I was thinking of cutting some rigid foam, or squishy foam, to fit in the spare wheel well to hold the jack tools, the chocks, and maybe some other stuff.

Other tools, and sparefluids in the tool bins.

While you're at it, do you have a small bag of regular lug nuts in there? Mine did- for the space saver tyre, in case you have ali wheels.

No space saver in the early cars or alloy wheels from the factory at least here in the US. The lug nuts are on the list in my 78. By then it was entirely in English.
