Camaro Z28 heavy duty parts list

[69Z28-RS]

Were the GM listed HD shocks (Konis) single or double adjustable??

They are single-adjustable. I've never seen a set of double-adjustable Konis with a GM part number on them. I don't think the double-adjustables became available until 1968 but I could be wrong about that.

Koni's were called out on the 68 Firebird section in my PHS docs I recieved for my HO 4 spd GTO. I had not realized they were an option previously. They are listed for factory billing, whether or not any were installed I haven't a clue.

Here's the 1967 Z-28 HD parts list, courtesy of Warren Malkin. The first item on the list is the rear spoiler which ironically was not available to any but a few select race teams in '67. The part number was catalogued so that it was legal for Trans-Am racing but was not available to purchase. Interestingly, when Joie Chitwood wanted a spoiler for his Camaro, GM provided him with a blueprint instead of the part so his car builder (Bob Tucker) had to fabricate it himself.

But how necessary was the blue print, since Donahue ran his spoiler extra tall?
Did it kinda give you a square 1 to start from and then you could modify it how you seemed fit and what you thought you could slip past the officials?

[Jon Mello]

A blueprint would give you an overall idea of what it was supposed to look like. If you wanted to take liberties from there, that was a risk you had to be willing to take. I can't find a picture of Dick Stanton's car showing his rear spoiler but it is a little lower than stock height so I guess he played it conservatively.
