BC-12D with C85-8F using stock engine mount?

[gcgilpin]

Is there an STC that covers installing a C85-8F using the stock BC-12D engine mount (presumably originally intended for the A65)?

I know a guy selling one like this but he doesn't have any paperwork to back up the C85-8F installation.

The airplane works great but the paperwork question bothers me.

Yes there is an official STC for this. It is called the Harer STC, formerly the Gilberti STC.

There are also several "field approvals" that have been done in the past, allowing this engine upgrade but not having some of the problems associated with the Harer STC. The STC (if done to the letter) is about three times as complicated and cumbersome as it needs to be.

If the serial number is late enough it could be installed with a log book entry as a BC12-D-85

How late of a serial number would that be?

Is the C85 listed on the type certificate?

THIS CAN BE DONE WITH A LOGBOOK ENTRY?
