Subject: [Roadsters] Space-saver spare for a Roadster

Has anyone sourced a space saver-type spare tire to fit a Roadster?

I am taking the first baby steps to getting SRL311-13291 back on the road after 35 years. Today I put vehicle dollies under the rear wheels and saw that the right rear tire, which I aired up last September, has a split outer casing – which it didn't have in September. It is holding air, which is kind of amazing, but the damage is quite impressive. Increasing the pressure in an old and obviously brittle tire must have split the outer belt. 

This reminded me that I will need to replace the spare – which is an original bias-ply tire and so brittle/shiny that it looks like a glazed doughnut – and I would like to put a space saver spare back there to recoup a little precious trunk space.

The rim is indeed four-lug, a Topy 14x4.5, the OEM supplier, I believe, from=
 a Datsun 260Z.

But I see the confusion I created, as it is actually a C78-14 space saver sp=
are.=20

Not sure where my brain came up with G78=E2=80=A6
