The FWD Rover 75 manual gear lever surround won't fit though. Unique to ZT 260. Even the R75V8 one is different to the R75 FWD auto version; no commonality.
Alternatively you could have everything professionally painted up in BRG body-colour? Matter of taste, but a fairly original looking solution?
Even the steering wheel is do-able, having seen one done in Typhoon/leather instead of "wood"/leather.
If you haven't already done so, you should read this HUGE thread about #027, also in BRG. Fantastic read.

Posts #44 and #143 or thereabouts (and maybe more), show the dash in BRG. Steering wheel standard though. Some interesting, if probably expensive seating and interior trim too. Much of that thread is also to be seen in the MGOC 'Enjoying MG' monthly mag, which you can still see electronically on-line on the MGOC site. in 'The Monster files' articles, were published bi-monthly between September 2020 and May 2021.
