If it's anything used on a Mustang of any vintage, they might have it. I see they sell the Tremec line. Or Jimi G might be able to help.
My 390 is swinging on the hoist waiting on the clutch from DKee. Also have a cradle coming from Stumpy that will allow me to lash up the engine and tranny and make sure tab A goes into slot B
