85 Heater Core=Cut Box To Replace?

[Fox Body]

Hey man,

thanks for taking the time to write all that. I read it all-- interesting and entertaining. But, after reading it all, can't seem to remember the key points. ... Basically, you cut a part of the front of the heater core box and just broke off the top?... Could you like just write the few key points about the modification of the heater core box, without all the story. Like 1), 2), 3).
