MSD capacitor box replacement...

The alternator died, on my 5.9 Magnum swap.... I jumped it, with the family truckster... It ran weakly, without the multiple spark under 3000... The box is still good, with the correct voltage, of course... I have had a couple of digital HI -6 boxes, wasn't really impressed.... I was looking at the designed hei conversion plate, for the GM 4 pin HEI setup... Any opine , would be considered welcome.. (Anything with multi spark , or added dwell stretch ..I would love to know about...).......
