I'd recommend that you speak to Barry Campbell from the Sydney club, who can
rebuild your Distributor and - more importantly - regraph it to suit the
specs of your engine. Check a yearbook for Barry's ph number.
25D6 and DM6 distributor caps are not interchangeable.
25D6, 25D4, 23D6, 23D6 are all the same family - everything is
interchangeable - you can make a 4 cyl (25D4) into a six cylinder (25D6) by
interchanging components. But nothing (other than the rotor) is
interchangeable between a DM6 and the 23D/25D family.
Do you have webers or SU's? If you have webers - I'd be thinking about
looking for a 23D6 (no vacuum advance) - which is what the works triple
weber Sebring cars used (at least in 1965 eh Joe).
Are you using the dist tach drive housing? BJ8's - which ran the 25D6 - have
an electronic tacho - the distributor has no provision for driving the
tach - so you'd need to put the gear off the DM6 on the end of the 23/26D
shaft.
25D/23D family distributors generally have a slot drive on the end of the
distributor - early 3000 DM6's have a gear drive (for the tacho). Austin
sedan DM6's are slot drive (they don't have the tacho either).
