I am trying to properly identify this factory phenolic carb spacer.
Any info is greatly appreciated.

I don't know how many applications it was used on but it was used on the 68 GT350 and also 69 GT350 up until about the end of March 69. It is a hard to find piece because the steel nipple broke easily when trying to take the PCV hose on or off when under the carb. It evolved to a better design in late March 69 and it was typically replaced with if it broke. that early style was not serviced much after 1969 and became obsolete so hard to find not broken.
