i got the cover leaking like crazy and i am having problems finding a replacment its a 77 L6 4.5L 250CID

iam trying to find a new one because i am thinking i might have bent the thing trying to pull it off the engine without realizing the were bolts that come up through the bottom of the oil pan

i know this is a 6 and in the wrong Section i just would like some info on where to find a replacement cover... thank you.
