Be very carefull about it. The last batch of radiator supports for the 70-72 Skylarks I bought from GM before they went discontinued weren't made worth a chit. Big fitment problems like they weren't spot welded correctly. Sorry I cant tell you how to tell when it was made so you are on your own. $750 does sound a little steep. I sold these last ones for $350. Mike Garrison out of Kansas sells patch panels to repair them though. He posts on the boards but I dont recall what his user name is.
