How large is the opening in the radiator support? The rules specify a "full-size stock radiator"... "of the same year or model", so I'm not sure you could use an aluminum replacement for a copper/brass OEM. Most vehicles had different size radiators installed for each engine they had, V-8's with A/C being the largest, and as long as the new radiator mounts the same way as the old one, you shouldn't have any tech OR cooling issues.
