I think what most folks do is drill the adapter
that couples the '67 to the focuser.

Given that there is a flattner lens in the 
OTA direction, the dry air has no where to go 
but into the camera and out the vacuum back.

(Note: I dont have a vacuum or dry air purge on
my camera/OTA.  But I too have considered it, and
the above is what I gleaned during this research.)
