Most of the Original Ford Condensers I've tested on my Ford Heyer stroboscope have a high probablility of being good. Especially the NOS ones. I'll take an original Ford over a NORS any day. You can almost place a 100% bet that a NORS unit will be bad. If you want one for your driver buy the A&L burnout proof unit.
I believe the "A" should be .23-.25 microfarad in capacitance, The must also be tested for leakage and resistance.
