I have a 77 ranger with tan interior as well. I have not seen any reproduction armrests in tan. The ones they do make in other colors are not quite the same as originals. They are a bit smaller and not as “beefy”.
You can occasionally find originals on eBay. They are the same as Econoline and F100 arm rests. If you end up using vinyl dye, SEM has some colors that are close. Both Palomino, and Santa Fe are close matches but not exact. You can have some SEM vinyl dye mixed to match the old armrests and it holds up very well. It’s difficult to get the front and rear armrests, rear quarter panels, and seat backs to match without having to dye something.
Here is a pair on eBay:

I’m not sure where to get houndstooth. I have covered my seats twice. Once with NOS cloth from an obsolete material supplier and then with covers from Bronco Hut. Both of those suppliers are gone…. I would save the old covers as patterns and for color matching. I wish I had kept mine 24 years ago.
Here is a NOS Tan armrest in the bottom of this pic and a reproduction on the top.
