Who am I responding to?
Can't answer your question for sure, but doubt it as the attachment point needs to be substantial to do any good. My Kosola units were planned with replacement of a rotten headliner which made things very easy. In your case, I would try to peel back the existing headliner enough to rivet as necessary. Then re-glue. The shoulder harness is a mandatory feature in my opinion.
Also be aware the NE Tribe is attempting to put together a group buy and install. See the article below for more info.

Shoulder Harness initiative: Shoulder harnesses, unfortunately not original equipment in most Comanches, are critical safety devices that save lives by protecting your noggin from your panel in the event of a sudden unplanned stop. This is a Technical (Zach Grant) and Safety (CJ Stumpf) committee initiative to provide a volume discount and fixed price install to Comanche owners. There are two STC’d providers of shoulder harnesses on the market: Alpha Aviation and PhilAir. Both have kits available for under $1,000, including inertial reel options for a few hundred more. We have spoken with both vendors and are in process of identifying shops across the globe willing to provide a fixed price install to Comanche owners. We are gathering a list of interested owners, using that to arrange bulk purchase, and providing a list of shops in each geographical area willing to become experts and provide a special set price for ICS members. We are also making provision for headliners since some of our aircraft have fragile or already-damaged headliners, and shoulder harness installs can be (and sometimes must be) combined with headliner installs. This is a potentially lifesaving service ICS can provide to its members. (As a person whose life was personally saved by an airplane shoulder belt, I am strongly behind this). The more people who are interested, the better the prices and the more shops who will be willing to become listed suppliers. If you are interested please email
allenmurray@mindspring.com with info/interest in participating. Please put Shoulder Harness in the subject line and include your year and make.
