There are only two options out there to my knowledge, and both are produced by the same manufacturer. There's the Original Ford Tooling manufactured by Dashes Direct (also known as Universal Urethane, in Las Vegas). And Dashes Direct also makes a reproduction pad, from tooling that they created themselves.
The Ford Tooling pads are almost double the cost of the reproductions, but close scrutiny reveals a slightly-crisper-contours and overall nicer pad with the Ford Tooling. So you've gotta choose based upon the priorities of your car and your wallet. Once in, most people won't know the difference, but you will.
Scott Drake is just re-selling the Dashes Direct pads. You can find these same Dashes-Direct/Universal-Urethane dash pads at most any Mustang parts supplier (at a lower price hint-hint).
To clear up any confusion, Universal Urethane adopted the Dashes Direct name year ago, ostensibly because it's a better marketing-name for their line of dash pads.
