Does anyone have an STC approval for a second oil cooler? Preferably NOT on the rear baffle. We used to have one to install the GPU style cooler which works great on tow planes, but I cannot find the paperwork which goes back to the early 70's. Or, does anyone have a Harrison model AD06CU04-02 oil cooler? It is part of an early Piper service letter for Ag Super Cubs to install a second cooler on the left side of the boot cowl. This early cooler had two fittings on one end. Need urgently and any help appreciated.
