There is really no reason to externally bleed the rear heater. The
coolant path gets the air out their quickly.

Unless you make or find an M10 X 1.0 nylon capscrew (bolt) your only
worry
will be that you strip the tapping in the heater core.

I once had to resort to substituting a stainless capscrew for the
bleeder in
a rear heater core, but, once the bleeder hole in the heater core was
plugged
I did not want to keep running the capscrew in and out of those plastic
threads every time I was going to bleed the system.  So, before I wrung
it in, I
grooved it for the O-ring, drilled it through and tapped it for a
smaller
capscrew which was installed with a fiber washer (it's a good way to use
up old Amal
carb kits).  The small nested screw became the bleeder with the M10
capscrew
staying put whenever it was time to vent the coolant system.
