The #S2360-1 is the latest part #. This is a common part to Turboed TCM's I believe . Don most likely will have it. He's in OKC. Try him first if he dosn't have it I would venture to say he would point you the right way. Permier has it for $124. Your Dad's plane looks nice. Where is it based around Dallas?
