I have decided to resore my original Harrison UP code 4 row. Both my 11-year-old aftermarket and my old Harrison that I had saved would need new cores. The price of restoring either radiator and the price of a new one are close to the same (unfortunately about hokies1984 cost level rather than David's). Bottom line, my quest for originality swayed the decision.
The radiator shop seems to be very good. They are going to do some additional restoration of the original Harrison beyond the usual recore, clean, and paint.
I have ordered new shroud clips and a UP code tag which the shop will solder to the tank.
