David, No. In GT2-L .... "Rocker arms, push-pull rods, etc., are prohibited".
There were a few cars built with rocker and push-pull rods before this rule and they are grandfathered in. [A few Minis with rocker arms and Jack Beck's Alfa with push rods.]
Here's a photo of the Fortech Mini's pull rod front suspension (2004), maybe. I haven't tried to uplaod a photo to this site, so this is a test. The Fortech Mini's sister car that Richard Kraus won the the 1993 Runoffs with, had the earlier push rod suspension. Also David Rugh's GT3 VW had a push rod suspension.
