Original alloys for a 1981 GLi Cabby?

Hi, hoping someone can enlighten me here.  Our GLi has got Pirelli alloys on it (the ones with the little P shapes cut out around the edge), but the one in the boot is different and is white.

What kind of alloys would have been original to it?  We're debating between us whether to keep the Pirellis or sell them and get some spoked ones, which we think might look a bit nicer.

We've decided to try and keep it as original as possible to a certain extent as it's getting on a bit and it would be nice to preserve it as I haven't seen that many GLis around.

It would have had 9 spoke alloys originally.
