I'm looking to outfit my SA with Plaid seat inserts,

I have friends that have bought the Racing Beat covers. I was very impressed with the quality and fit and I know the covers are made to order.
Inquiries to racing beat asking If I could send plaid material to be put into their seat covers went unanswered.

So, I'm wondering if anyone knows the name of the shop that is local to Racing Beat that actually produces the covers so I could contact them to see if they would accomodate my request.
I would still place my order through Racing Beat, if I could arrange for the covers to be made with the material I send them.

 

The place where Racing Beat used to get their covers is Seatz Mfg. I bought a set directly from them years ago. As far as I know they are still the supplier.
