Found 'em!
Yeah, These nuts are hard to find, I think that there are only two used on the whole car. I ordered a Front Bumper guard kit from two separate vendors. One was a Scott Drake Kit, and it had the two "rare" square "U" nuts...!! I also ordered an AMK kit, and to my surprise, They were NOT in the AMK kit.. The AMK kit just has the generic longer "U" nuts and not the Shortie Square correct "U" nuts..
Well, I've got what I need now with one exception.. I'd like to know what the supposed "correct" hardware bolts and clips for the Front Bumper Guards (Bumperettes)... I have it all, Just need to know what is most correct...
Otherwise, It's off to the Factory assembly manual though I know production sometimes differed from that manual.
Thanks,
