I am pretty sure I have a C-152 engine mount. I purchased it to hang a O-320-E2D on a stand.
Unfortunately, I am not totally positive, and did not look for any identifying markings before I hung the engine on it. BTW the O-320 does not fit on the mount perfectly, however, this may be due to the way the engine lord mounts were done.
Anyway, I am looking for a good, non cracked up firewall for a 1965 project, and the 1966 is the same.
