With points, the distributor will work with either polarity. If you want to
use a Pertronix conversion, then you'll have to get the one that matches
your polarity.
I believe TRF P/N PTR114 is Pertronix P/N LU149; which will work with DM2
and negative ground. (The positive ground Pertronix number is LU149P12.)
However, it might be available cheaper from other sources. I found a
listing on Amazon for $96. I got mine on sale at FLAPS for $80, but that
was a few years back.
