upper control arm brackets

[59chevy]

hello, nice forum you guys have here. i have a question that is pontiac related. years back a friend of mine bought what he was told was a 1973 herb adams fire-am. we had removed the engine for a rebuild and there were a set of y-shaped bars running from the upper control arms to the cowl area, when it cane time o put them back in he decided to toss them in the trash, having a camaro i grabbed them and they had spent the last 15 years in a shed. are these bars herb adams specific and are they worth anything to a person with a herb adams trans am or are they still available. i really cant find alot of info on them and am really tierd of looking at them as now they are getting kicked around my garage. thanks..
