Sorry about your hassle with CI. If you search here will find we have a lot of complaints. The 3 biggest are hocking Camaro parts that don't fit as Firebird parts, insane shipping costs, and sales that seem to never apply to the parts we want to buy.
Ames Performance Engineering is my supplier of choice for an FGF. Performance Years is also up there. You will also find useful editorial comments in Ames catalogs about what fits and what does not.
PS, my wife is from Jeanette, PA down the road from you. I have been in that area a few times.
