Art,
Can't you just cut the ends on the leads and fit them into the side entry
cap?

Subject: Re: [TR] Name that distributor (TR3)
Thanks Randall,
Yes they sent me LU422318 according to the packaging. It appears from
britishvacuumunit.com that that part along with LU54413549 (moss 153-640)
might work, although it's not clear from any of the photos if that terminal
connector is meant to fit *over* the fork of LU421078 or *instead* of the
fork.
To further complicate things the internal contacts on my "up style"
distributor cap are pretty crappy and I have a brand new sideways style unit
I picked up somewhere, but that means new leads. sigh....

40480D is an earlier model DM2P4 distributor. The information I have handy
says 40480F (which is functionally the same and still DM2P4, the letter is
just a revision level) was used as late as 1959 TR3, some of which were sold
in 1960.
That same database says cars built in 1960 got 40698A/B, which is still a
DM2P4.
The Moss catalog is certainly misleading, as they show a drawing of the
plate for a DM2P4, but the listing says it is for a 25D4. They have no
listing for the earlier part (which I assume means it is not available). I
believe the equivalent part number at TRF would be LU421078, which they have
listed as NLA. You might check with Revington, he seems to source a lot of
parts the others can't find.
Faced with that same dilemma some years ago, I fabricated a mount for the
low tension lead that worked quite well. Just a stack of pieces of bare
fiberglass printed circuit board (from the scrap bin, no copper plating),
carved with a Dremel to fit snug but not too tight in the slot in the
distributor cap. A small bolt through the center linked the two wires.
IIRC I used 3 pieces of PC board, one smaller to fit inside the notch and
two slightly larger to fit on either side of the notch. A little extra work
to install the cap, as I had to hold the side wire to position the new piece
in the slot, as I lowered the cap into place, but not too bad.
Later, I switched to a (used) 25D4 distributor.
