Howdy,
I'm looking for the actual paperwork for C85 STC (SE00979AT) that replaces many parts on the C85 from an O-200. My logbooks are missing that detailed STC although all the aircraft logs reference the work being completed per the STC.
Searched online but couldn't find any detailed copies of the STC.
Thanks in advance.

This is the STC held by Aircraft Specialties Services Inc. It replaces the crankshaft, connecting rods and pistons with those from an O200. Contact them for more information.

Current price for the STC alone (with data plate) is $225. It is listed as "out of stock" but think that must refer to the 12k kit with crank, since presumably they did not run out of paper.
