94 Caravan heater core

I`m replacing the heater core on my brothers 1994 Caravan (3.0 engine, AC) and have taken everything apart on the dash, in the engine
compartment, etc..I`m now at the step where the manual says, "Disconnect the hanger strap from the heater/air conditioner assembly and bend it out of the way".....This is suppose to be the final step befor pulling the big black plastic assembly out.....My question is..What are they considering the "hanger strap"???..It seems as if the entire large plastic assembly is trapped behind a series of interlocking metal braces which the dash pieces screwed to...Is that entire bunch of metal braces the "hanger strap"....If so there`s no way to simply "bend it out of the way" it all seems like it needs to be removed..Thanks in advance
