Huh ?  Then why does TRF's catalog list P/N PTR101, as "Pertronix, TR2
models with positive ground and Lucas model DM2 distributors" ?

So, if that's the only problem, why not source a point plate ?  If memory
serves, the point plate from a 25D4 should drop right in; and allow you to
use your choice of either positive or negative ground Pertronix units, or
even points if you want.  Used 25D4 dizzys frequently sell on eBay for under
$20

(that one's for an MG obviously, but the point plate and most other parts
are the same for all 25D4)

Another choice would be to fit a Crane XR700, which is "one size fits all",
to your existing dizzy.  It's more trouble to fit, but should work fine even
with your mystery point plate.

What about a Lucas 25D4 ?  Ask around your local club, I'll bet someone has
one they'll part with cheap.
