Coupe GT retrim

[84CoupeGT]

Hi everyone

I'm thinking ahead to when my Coupe GT is on the road hopefully next year, and getting the interior retrimmed. The seat fabric has been replaced at some point and I'd like to get it back to the original with fabric from Audi Tradition. I know they're not delivering to the UK at present but may have an option of getting it delivered in Germany and forwarded on.

My question is, does anyone know how much of each fabric is needed for a full retrim please? I know the "Karo Tweed" checked fabric goes on in the seat squab and backrest centre parts, and the door cards, and the "Uni" plainer fabric goes on the headrests and seats bolsters, surrounds, backs etc.

My interior currently:





What it should look like (not moving the steering wheel though!)





Cheers for any help!
