No problem on an aluminium rad Roger as its of tig welded construction and I just tig welded the new brackets to the sides which do not contact the core, however if yours is a brass/copper construction you have to be careful as you can easily melt the solder joints, solder melts at a much lower temp than aluminium.
But having said that I often tig weld brackets to ordinary rads without any problems as the have steel sides
