Re: replacing points 4 good with nissan pulsar distrubitor?
I wouldn't bother stripping and changing internals. Why not remove the gear of the A12 dizzy (The timing gear) and put that onto the elec dizzy? This is wot I've done, (although my engine is yet to run) and it seems to me that this will work. Yu may have to make a new timing plate.

duh me! I just realised this morning that you have to use the A-series rotor button! everything fits now, just have to drill the hole for the drive pin and file out the hole that the rubber seal on the ignitor lead sits. I should have really done a photo essay on it,
but I don't have a digicam and can't be assed about scanning regular photos in.

Strip the whole top assembly from each distributor and put the E15 bits into the Datto
dizzy- it is VERY EASY!
nope, tried that. I pulled both of the dizzys apart today and had a bit of a ponder. the
assembly out of the E15 dizzy goes into the A series one alright, but the cap doesnt even
come close to fitting over the (much bigger) rotor button. added to that the E15 uses screws to hold the cap down , whereas the A15 uses the regular clip style. and there is nowhere to drill / tap holes anyway seeing its a wider cap. What I have sussed though, is
that the E15 should fit quite easily. the only real things being drilling a new hole in the
shaft for the A series drive gear pin, and allowing for the difference in positioning of
adjustment plate. luckily the plate from the A series unbolts from the bottom so I should
be able to attach it to the bottom of the new one. oh and the vac advance units nozzle on
the E15 points the wrong way (down) but the A one fits straight on, with the exception of
having to drill and tap a second hole.
There are two wires coming from the dizzy the black & white one goes to positive coil & the blue one goes to the negative coil.
