The contraversy begins... Did the Porsche factory issue this document or was it created by one of the Porsche Authorized Distributors racing teams? Which other 914-6 GT had this modification implemented and by who? Do you know? Besides the “Lufthansa" and the "Collier" 914-6 GT cars, are there any others? Too many questions and not enough answers yet. This document was obviously written in German and maybe our friend "Bernie Buschen" can translate it for us... :)
