I have two rear hearter from under the back seat of my 87 and a parted out
87.  They both are leaking out the plastic on the side (near where the hoses
attach).

If I was to order a new heater core, would that only replace the core and not
the plasic box that the core is housed in,  will that fix my problem?  Does
the plastic not hold coolent and if the core is dead it just LOOKS like it is
leaking from the plasitc and is realy coming from the core?  Please help...
Its COLD outstide!

Thanks
Tim
