Try out your Holden dealer.
Take in your VIN and get the part numbers of the seat assemblies you require and see what is around the place.
I replaced my drivers seat foam and they wanted the VIN as seats' change - eg side airbags etc. My driver's seat has two motors. Manual lumbar support, and front - rear push down slide bar. No side air bags. The material is red cloth with a red/black cloth mesh infill. You can see the colour differences in one of the images.
There are stickers on the seat frames to give you the best chance of the correct seats.
Pictures are the drivers seat.
I think the upholstery colour was Anthracite red or black if that helps.
