Need a reputable radiator shop to re-core an Oliver Super 55 radiator

[super55]

After years of battling Autumn Olive with my trust 1957 Oliver Super 55 it finally inflicted some revenge. I stick punched through two of the 3 rows on the radiator core. Tried to solder and braze but getting enough heat to the middle row melts away the outer row's copper rib. As it stands right now getting a replacement is near impossible. Called several sites and all are on indefinite backorder and have had no luck finding a used one. The upper and lower tank are brass and are in great condition.

I know a 550 rad. should work because its a late model Super 55 but can't find one of those either so anybody who knows of a shop that does good work on rebuilding them and will ship the finished product let me know. Thanks
