Default '69 Heater, Blower ***'y "Spl. Washer"?

Does anyone know what type of washer the AIM is referring to? (see pic) I've had no luck searching the forum and a google search returns GM Parts Wiki references to obsolete parts. It looks like it's sandwiched between the firewall and the blower housing.

GM P/N 3868762

Thanks,
-Doug

The 3868762 washer was a mastic washer .25 X .80 X .12 in size... This was just a sealing washer that you could replicate with some strip caulk around the stud before you install the box.
