I pretty sure both upper and lower radiator support pieces were original spot welded on. As to bolts to attach fenders I would say go to ebay and search e-body fender bolts, you'll find full bolt/clip/stud kits for attached both fenders.
Great - thanks! And what about the junction where the top support meets the apron; do you know if it's spot welded there too? I appreciate your help.
I had the same idea about the bolts right after I posted this.. I'll be able to find it there. Thank you!
