Congrats Marlin for realizing the need, and responding to that need. You began selling the thermostats at a time when they weren't available, a year and a half ago. You've been reproducing the brass restrictors much longer than that. Your parts are always identical to the factory parts. You've been a trustworthy resource, helping the owners of 351C powered cars around the world in keeping their vehicles on the road, and you have my heartfelt thanks.
