Depends on if you want 68/69 Stock valve covers that are chrome....or just any chrome cover that'll fit. If you want 68/69 correct - your best bet is to have a set chromed. They did come chromed from the factory for some applications (69 Stage1) but after 35 years most of the original ones need a re-chrome anyways.....and thats all they basically are is a stock 68/69 cover that the factory chromed. If stock is not an issue, any 67-76 Big Block (400, 430, 455) cover will fit. Also, there is aftermarket too. Someone recently started making them infact - take a look on Ebay as I've seen them listed there....also do a search here as they've been recently discussed as well.
These will work, if originality is not an issue. They are correct for 73-74 Stage1's http://www.v8buick.com/showthread.php?s=&threadid=48091
