So...
On a similar thread, I need a new radiator. A local shop says they can re-core my original for about $550 --estimated before pressure checking to see if it's a more minor problem. KW has one for $565 new. Is there any sound reason for me to have my original radiator repaired over getting a replica? Also regarding aluminum: I've been trying to keep my jeep looking as original as possible. Would substituting a cheaper aluminum radiator be too big a compromise in anyone's opinion? I imagine there could be a lot of pluses going to an aluminum radiator.

For anyone in the Pacific NW that needs radiator repair, Macs Radiator, https://www.macsradiator.com, is three generation family owned, reputable, will seemingly re-core or fabricate anything and they have multiple locations from Boise, ID to Portland or Eugene, OR.
