I have a fiberglass seat base for a Fiberfab/CMC VW based MGTD. There is only one, and there is a 4″ speaker hole cut into it. It is free to anyone that needs it. It is located in Memphis, TN. I’ll box it up for shipping. just cover the shipping and it’s yours. I don’t know the weight, but it will probably be pretty cheap to ship UPS ground. I can send pictures this weekend. I think it is the passenger side, but don’t know if that makes a difference, I’ll check the label on the bottom this weekend.
