Front endlink strut mount hole ?

[lsupcar]

I have had a front end clunk for many years. Recently, it became apparent the sway bar end links were in need of replacement. I replaced them today, and the hole in both of the strut mounting tabs were oblong, but symetrical side to side. Is this the way they are supposed to be? Or are they supposed to be only a round hole just the size of the end link bolt? If the are supposed to be round, how can I repair the problem? Thanks. I went ahead and mounted the end links as best I could tightening the bolt as best I could in the top most portion of the hole.
I am having trouble loading pictures. I will post this and try to post the pics later.
