88 heater core replacement

Looking for some extra hints on replacing my heater core. I just received my jeep a short time ago and a few things need fixing. Obviously the heater core. I have the blessing of a heater core from another year but still a YJ series. Does anyone know if that will work? If so I will not buy another core. If someone is willing to write a brief walk through or send me a url to a walk through i would be highly appreciative!

There is no situation that cannot be improved with a small but well-placed explosive.

Just replaced the heater core in my 87. The cores are cheap enough to buy one that is new. Also, look at changing your blower motor while you have the plenum apart. It took me about 2 hours from start to finish.

This is what I used as a guide to help. It was perfect

I believe they are all the same on YJ.

But simple enough to figure out if you take 5 minutes and compare the part numbers on a site like www.rockauto.com.

More importantly, I would make sure I used a core that has the mounting flange welded on. Most of the knock-offs don't and they just bounce around in the plenum. Works, but it ain't right.
