That's usually the first thing everybody here harasses a new FEP member about providing. ;) If you say hello in the 'General BS' section, you'll get a bunch more welcome messages without doubt. :)

To help prevent this problem in the future you could install some coolant flow restrictors in the heater hose. This will in effect cut down on the water pressure the core sees. too much internal water pressure will split one wide open. The fox police cars had them as OEM. Sorry don't have a part number handy.

I lucked out and was able to backflush mine and get good heat :twisted:

If its a 25 year old heater core, I hope you don't expect it to go too far before it gives out for good.
