Other than to give Joel Reiser or Jeff Gamroth a call, no
there aren't too may sources for these antique race parts any more and afaik PMS doesn't support the 993 anymore either though some of the suspension parts were available as late as last year so maybe give them a call too.

Chris Cervelli, here in Denver, might know where to find those sorts of parts. Rodger at Orbit and Pat Williams also come to mind.
If you get really desperate I guarantee you can get them from Freisinger out of Germany, but expect to pay a premium price.

You have several options. FVD has a rocker that works. It is a 993 rocker modified in similar fashon to the 993GT2 adjustable one and are PCA legal. Neil at Performance Developments can take a set of factory 993 hydraulic rocker arms and convert them to 993GT2 rocker arms.
The factory GT2 rocker arm uses a special adjuster that uses a Torx head with a 1.0mm thread pitch. The converted rocker arms "generally" use the standard 901 rocker arm adjuster.
I've run all of these rocker arms with no issues.
You can also try a 901 rocker arm with the splash lubrication hole pinned, however, these rocker arm tolerances vary quite a bit so you get varying amounts of lift and some of them have to be machined down so they fit inbetween the cam tower bosses. I've run these as well with no issue.
Basically, good luck getting anything out of PMNA that isn't 996, 997, or 991.
Give me a call if you need details on any of these.

Thanks all. Geoffrey this is Joe Bank. You checked out my 993 Cup for me. You should see it now. Pretty much restored. Chris Cervelli is doing the work on this. It seems I have several options now and just need to acquire a set. Geoffrey if you ever make it out to CO give me a ring.
