Please Help Me - Posting for my 70 year old grandfather

My grandfather is trying to find the best place to buy seat covers for his 1970 Plymouth Duster (340). He calls me on the phone and I do my best to look these things up, however he is concerned with the ones we have found so far and is trying to find something that isn't going to be made in China.

Thank you all for your time and your help.
