Well, from all the replies I see that it is welded on, and Avey had written to me saying I can drill out the welds. So once I drill out the welds and remove the rad support, can I place the new one in using grade 8 hardware?
I'd go to a u-pull-it salvage yard and pull everything except the rad support which I cannot do myself without my electric drill on site. The rad support I can buy for less then $100.
