<VV> Dash harness trunk penetrations

[Doug Mackintosh]

Need some help! 
 
I'm trying to find the grommets for the dash harness wires that enter the trunk in the upper left corner of the trunk. The car is a 1964 Monza, but my 1962's appear identical. A bunch of wires from the dash harness terminate in a round plug which is pushed into the trunk through a 1.5" diameter hole. It appears there is a rubber grommet with a groove on the OD which snaps into the 1.5" diameter trunk hole, and a groove on the ID which the 1.3" diameter harness plug skirt ridge snaps into. 
 
Does anyone know where to get one of those grommets, or what works as a substitute? It is missing on this car.
 
Also, there is a rubber grommet to fit the 1" diameter hole in the trunk just inboard of the 1.5" diameter hole. This grommet has 2 small holes for the two sets of wires going to the wiper / washer in the trunk. I know I can modify one of the 1" grommets I can obtain, but does anyone know where I can get the actual grommet with 2 holes for this?

Thanks!
