So my friend's family owns a junkyard and they recently  acquired a late 80s Subaru GL wagon that was totally trashed in every manner possible (interior looked like a buzz saw went through it, engine compartment appears to have had a jug of oil explode within it, the paint job is a wreck, etc...  ) The poor fellow had 245,201 as its final number on the ODO. (Taps playing in background)

On the bright side, I got some great stuff for my own wagon. Back-up Ignition coil, front wiper motor, blinker dome, extra oil cap, ect, ect. I also grabbed the dead soob's coolant overflow container. Im not sure what year it was or if its an EA82 engine or part of the EJ series of engines but my question is: is it possible to make this overflow container work for my EA81 wagon(Which doesn't have one)? or is there some technical detail that would hinder the coolant overflows compatibility?

yes, but need to ensure the radiator cap is the recovery style with a second seal in it. I have been running an EA82 bottle in an EA81 for years, also run another non Subaru recovery bottle mounted up near bonnet hinge and long hose across radiator and along up to bottle - great idea !
