Hi Bill! 
        Yes MFD means uF. It's from the old days when radio/electrical techs 
didn't read Latin or Greek. I can't tell for sure from the label and there's 
nothing in the pic for size comparison, but those look like electrolytic 
cans. If so, they are for DC filter circuits and will burst under AC 
operation. If they are marked to indicate polarity, don't use them.You want 
motor run caps, not motor start caps, ballpark, about 250-300 uF worth.
