As far as I know from articles I have read the first few ealy ones, prior to the 505-506 option from Porsche Special Wishes, that started in 1987 ( some say 7 factory ones ) were built without vents. Alan Johnson racing built this one ( 1983) with what appears are NOS factory fenders left over from when Porsche supposedly switched over to the vented ones in 82-83. Hard to know how many NOS non vented fenders or completed at the factory were sold from Porsche that had access to these type of parts. Who / when built these cars in the previous posts? Here is a 79 930 built in 1983 - 84 by A J, still mostly original paint etc, as when it left AJ USA.
