ran into some problems installing my springs. for 1996 SS camaro

I'm looking for 1 of the stock orange de-carbon struts made by delco i believe??

their on my red SS and on my black SS, so im thinking their just the GM struts.

I got one side all done and then the 2nd front strut gave me problems, so now i need a strut. I dont want to replace both cause i just had it all apart and dont want to do it again. so i'm looking for the same as what ive got, and with some milage on it.
