I'm sorry I missed you yesterday, Chick.. I actually met someone today that knew you, and knew you weren't there today. I did get to meet quite a few great folks with super cars, and had some great conversations, and learned and shared information.. Which is the best part of such shows.
1) I found many more 'late' '69 Z28s that had 'dripper valvecovers'.. so it seems about 10:1 that the factory did begin using dripper valve covers sometime in the late summer.. no idea on the actual date, but some go back to late August '69.
2) I learned that late camaros used 'torx' bolts to hold in the door latch striker, rather than the 'hex/allen' used on earlier cars.
3) I learned that the late Camaros used the '70 type upper alternator bracket, with an additional larger hole in it.
4) I found out where the date codes are on the fenders and quarters, so I can now check those dates on my car..
5) I found that few restored Z28s with cowl hoods had date codes on them (confirming that not many Z28's originally came wtih cowl hood option).
6) I got to see and inspect the car and paperwork for the 'X11' coded Rallye green Z28.. I initially was skeptical upon reading that, but after talking with the owner, seeing their paperwork, and seeing his original (pre restoration) photos, I now am a believer, but I'd give anything to know how that happened; I believe it will be a very interesting story once it's ascertained how that happened. PS> He and his wife are great people whom I really enjoyed talking with at the show! and their car is gorgeous..
Note: their car also has an 'M' cast code block!
7) I met many more neat people with neat cars... too many to mention...
I can't wait to go back next year, in spite of the 14 hrs it took us on Thursday to get to Frederick..
