I won't do any welding there and the extension pieces they sent will bolt right up to the condensor but I am not too keen on the idea of bolting anything to the radiator. Putting holes in my $800 radiator for screws is not something I find appealing. I will get it all back out on the work bench tomorrow and inspect it all again but don't remember any areas on the radiator where I can put screws without danger of getting into the radiator core and causing leaks. Have a Vintique grille and Vintique grille shell which fit perfectly together and holes in shell mounted right up to the grille shell mounting tabs which US Radiator has on the radiator sides. but nothing on radiator for mounting a condensor.
