I have 2 customers with the old power centers sitting on the shelves, want me to see if they will part with the charge controller? No guaranty, 1 says he is going to move it to his camp and they're both pack rats....
The better bet is the MPPT controller but keep in mind that the original breakers are not rated for the series panel strings that we use now. The Square D breakers are only UL rated for 50 volts not the typical 70 - 96 volts we see now.
