When I did my repair over a decade ago, the amount of tanin leather hides was very limited. Mine was ordered from Germany.
You can try to find a match from another manufacturer or have a custom dye made. Even when I got my hide, the grain was a bit different.
Since my repair, my passenger side bezel has started to stretch and is exposed. I have just left it and live with it, even though I have some extra leather. I did see a few other posts (not sure which board it was from) where someone stretched their leather and secured it to the back of the plastic with miniature pins. Whatever method is employed it is a major job to get the bezels out (dash and console removed, separate bezels, find a qualified leather repair facility, then re-assemble). Leather dash covering is certainly problematic.
