Original R361 Radio Cassette

[Floron]

Hi there. Hoping someone can help with this.

I've got a 1990 Mini Racing Green which at some point has had the radio replaced with a new unit. I believe that the original unit would have been the Philips R361. I'd like to put the original back but it's hard to find this model anywhere on the internet, so was wondering if other period units might fit?
It's had a new dashboard so the radio/cassette now needs to slot into the aperture.
Thanks in advance!

The should be a standard 'Din' size so any single din head unit should fit.
