GTO John posted a pic a week or so ago of the bottom of a clean '72 endura coresupport. I'd get you measurements, but my #1 coresupports are in epoxy primer & wrapped up where I can't get to them. Needless to say, the bottom rail of your '68 V8 Pontiac A-body coresupport is the same dimensionally as the pic John posted, & the bushing holes are oval shaped to allow for side to side adjustment of the coresupport.
