Do yourself a favor and spring for genuine Lucas distributor cap and 
plug connectors.  Get solid (copper) core wires and make your own 
secondary wiring.  The plug connectors will have 15K ohm resistors to 
help suppress radio noise, and any plugs you can get will likely have 
additional resistance (I've had good performance from Champion RN12YC).  
Don't think you can get the Lucas cap from Moss (not sure--I got mine 
from Hemphill's--they still in business?), but if you get wire and plug 
boots they'll send a sheet listing the correct lengths for each wire 
(check with the salesman).  For authenticity, get the two rubber O-rings 
to group 1&2 and 5&6 wires (any suitably sized O-ring should work).  
Wouldn't hurt to use silicone dielectric grease inside all connectors 
(at cap and plug boots).  I bought the little yellow rings with the 
plug#--helpful plus they look cool.  Of course, this is for a "stock" 
setup; if you get a newer style cap with push-in connectors you can run 
newer style wound wires.

Test each of your wires for resistance before installing--it should 
equal the resistance of the plug boot (the wire resistance should be 
negligible for the solid copper wires).

I tried several of the "off" brands--including Bosch--and the caps 
always got leaky sooner or later.  FWIW, I've run a Pertronix ignition 
for probably 25K miles with no problems.

I ordered a bunch of rotors from Cape and have had the same one for 
probably 15K miles (had one non-Cape fail before).

Do this and then--and only then--can you start blaming your S.U. 
carburettors for all your problems ;)

I'm really surprised the car was running as well as it was. I'm going pull the plugs tomorrow and see what surprises I find. It's been suggested to not go with Moss for wires, any suggestions for cap or rotor?
