How ro find black Leather for 84 TE

[marcvv]

After someone hopped into my car with a screwdriver in his backpocket, I now need to replace the leather-side of the chair;

I've found several companies that can do the job, but they can't find a good match for the leather. The old leather is a relatively thin black leather, which is almost smooth (no structure/print).

Where could this still be found; or a good substitute ? pref. in the UK/Netherlands ?

Kind regards,

Marc
