Do you want the screened ones or the un-screened type?

Found a army reference list for spark plugs. Listed below is a part of that list that discribes the screened sparkplugs, including measurements and the "civilian" names of the products.

I've listed TABLE 1(b) below, that deals with the screened plugs suitable for Dingo's.

M.o.D. "Defence Standard" 29-2 (sept. 1974) regarding 
PLUGS, SPARKING (NON AIRCRAFT).

Table 1 (B) "Standard Range, Plugs Sparking - SCREENED"

(a) NSN: 2920-99-803-6570
(b) Service Management Code ARMY : 6 MT4
(c) Item Name : PLUGS SPARKING
(d) TREAD SIZE (mm) : 14mm
(e) TREAD REACH (In) : 1/2"
(f) SCREEN TREAD SIZE : 0.692 x 24 tpi

Thanks for the information. Do you know the modern unscreened plug that works best. I have been told I need a modern plug which is hotter.

The problem I am having is the spark plugs oil up. It was suggested a modern plug which burned hotter would at least in part solve the problem. Does not have to be a screened plug. 

When I take it on a long journey no problem. It's the short journeys which seem to cause the trouble.

As per my first post I have now fitted electronic ignition and conventional leads and plugs to my DAC.   The Green Spark Plug Company advised which conventional plug to use but obviously the code on any spark plug tellsyou its size, length and optmum temperarture range.

If it is oil rather than the products of combustion you have problems.
