I got the last of my parts in to do my heater core.
I finally have all of the parts!
If anyone is interested, here is what you need to buy and what the parts look like if you have to replace your heater core. If your car has a 9/96 or earlier build date, you need all of the parts. After 9/96 you would just need the heater core, but given the track recore of plastic parts on out cooling systems, I would replace the inlet, too.
As you can see, the new tubes are shorter
