Through hole replacement from one side?

I understand that now, noticed a few others mention it and in all honesty never considered it. There is a "but" in this circumstance.. there would be no way for me to know if resoldering created a good connection as there's absolutely zero visibility. making things worse, other resistors are very near and adding solder blindly could be hazardous.. Since this diy thing is supposed to be fun, i decided to go deep again (and again) but thanks for the input!
