From the usage info on CRG:
As noted above, the 69 NOR Z28's did not use it until mid-year, in the late January / early February timeframe.

Not to change the subject, but I realize that some cars came with the pressure release valve and some cars did not. My car is a 03D build and it has the valve. Did all the sub-frames coming down the assembly line have the hole for the provision for the valve.

^^
1968 LOS Z28
Subframe has provision No Valve:
I would hazard a guess that ALL sub frames were spec to have provisions i.e. holes for locating tang and self tapping screw for install of valve as needed.

My 69 Z and my 69 SS survivor nova did not have the valve. My 69 Z/28 still retains the original brake line from the booster to the rear end bracket. Both cars were November of 68 builds.

Salvatore,

As mentioned earlier, the pressure valve was introduced in 70 on the Nova. So wouldn't be on your 69.

CRG site says that early built Norwood Zs didn't use them until late January, early February of 69.
