So - a little follow up. I went with the KLA mounts. Car already had the KLA strut brace on it with the heim joint ends. Had a decent (non-Porsche) local shop put mounts in.
The mounts are reasonably priced and help from tech KLA was fine. Got them quick. I cannot really tell much ride quality degradation - honestly.
Bad news.....the rattle from the drivers side is the same. The drivers side strut mount (OEM) that came out, looks pretty new - I think prior owner was chasing this noise down too. Anyway - found shop locally w/ a mechanic who worked at a Porsche dealership for years. Gonna let him take a look.
I personally think these mounts (KLA) are fine to use if you can't fine OEM. JMHO.
