yj heater system swap?

I have just recently acquired an 87 YJ with the V-6 motor, manual trans. It is currently completely gutted and the body has been removed. I have access to an 89 YJ with the 4 cylinder motor, also manual trans(if relevant) in it. My question is, can I pull the full heating system from the 89 and use it in my 87? I am not sure if there is a difference between systems on the different motors? I never saw the original one for the 87 so I don't know how to tell if it is possible or if I need to look into an electric heater before the winter. Thanks for any help!

I'm pretty sure they should be the same between those years. I don't think they made any changes to the heater box through the whole run of yjs. Engine won't matter, although unless it's indeed a V6, you'll get flamed on here pretty quickly for calling an inline 6 a V6.

The heater box, controls, and dash (except the Speedo and tach) should be the same in the 87 -95 years. If your installing the heater box, I suggest swapping out the heater blower motor with a p/n: PM102 from an auto parts store. It really pushes the air.

Yep, they are completely compatible for the swap. And as far as the V6 if it is a true V6 its a Dauntless motor, and the last time they were put in a Jeep vehicle was the early 70's.

Ok good to know the swap will work. Also it is an inline 6, thanks for the tip. I didn't really think about it as I posted it, I am still new to inline motors. Ill have to pull the other one apart and see what I can salvage from it. Thanks.very much for the quick replies!
