Interior rework, need your opinions

[Red68]

I want to re-upholster my seat in my 68 and wanted to get some ideas from the board. I am thinking about using black / red houndstooth like the stock style with black sun visors and keep the gray carpet and black dash pad. Will the red houndstooth clash with the red paint if it doesnt match exactly?

What are your thoughts on the the seat idea and any other ideas.

I also want to replace my seat foam, I see at LMC where the bottom foam is the same for 68-72 but the back depends on the year. I know the seat I have is not the same seat that came with the truck. How do I tell what year the seat is and if I can order the foam back for it.

Thanks for any thoughts/ideas
