Thanks. That is very helpful. It shows what I'm describing as a core support as multiple parts. Below is a pic of a radiator core support for 90-93 Accords from www.andysautosport.com for only $59. Perhaps it is the same multiple pieces already put together?

 

Going out on a limb here...
Maybe from the "official" parts catalog, maybe those multiple parts are meant to be welded together, not bolted. So they may or may not be readily available as separate parts???
