Pulled my front bumper off this past weekend and on further inspection found that my core support was rusted under the battery and previous owner repaired, but poorly. Looking for a nice core support.
Not sure if a 69 is the same as a 71 but here's this one in "parts for sale" http://www.v8buick.com/index.php?threads/1969-radiator-core-support-and-inner-fenders.343503/
I’ve got one that was repaired by the previous owner way back before the patch kits were available. Send me your email and I can send you more pics if interested.
