...These are the actual Koni adjustable rear racing shocks used by the Porsche factory on the 914-6 GT cars. I found the first set of Koni shocks in bad need of repair which a subsequently had rebuilt to new factory specs. by True-Choice http://www.truechoice.com (U.S. Koni Distributor) for less than $290. I have since acquired two more pairs which I just sent to be restored. More photos to come once they arrive.
