Thanks Ken......Yeah I found the hole on the subframe and that is what got me to thinking about which one is correct. I did find a sentence in the CRG info on spoilers that stated the change in the production line to the later spoiler might have occurred in may '68...So that would place my 07C car in the later category. I am the second owner and when I purchased the car in '72 the spoiler was already gone so I am pretty sure the hole in the subframe was put there by the factory. Have you noticed the difference in spoilers on any of your '68 restorations?
Thanks again for your input......BTW....I am considering the prospect of having someone restore my Z28.....would you be interested? If so, let me know and I will give you a call.
