I am working on a Pawnee (PA25-235) that has an old STC (SA300SO) installed on it allowing for a 2nd oil cooler. The STC was added in 1965. The owner of the STC was Memphis Aero Corp and is apparently out of business. I am needing the installation instructions for this. Does anyone within the sound of my voice happen to have it? If so, will you allow me to see copies of it? Thanks in advance.

Sure, there are a couple of different cooler installation types, give me a call, 772-453-Nine999
