Source engineering in Coberg Oregon replaced my 2003 with brass/ copper just a few months ago. . My not be near your location but they were honest and good to work with. Radiator itself was about 3900 if I remember correctly whole job a shade over 7 grand , I replaced the surge tank also.
The labor on a side radiator replacement was a min quote of 15 hours ( source ) ,some quoted me up to 20. At 125.00 an hour it's a major consideration ! Peterson cat in Eugene also told me after the fact they had a good radiator supply house and did lots of them. Just FYI BCS quoted me ( verbal no hard numbers) about 9 grand to replace all in.
