The new lights have the seperate bulb for the parkers as you'll find all 7" replacement headlamps will now. Modification is pretty simple, provided you like filing or have a large enough drill bit (I don't).
Here is a run down on what I did.
1. Remove headlight surrounds.
2. Remove chrome retainer 3 screws (not the adjustment screws) and remove chrome retainer.
3. Unhook headlight connection, and remove headlamps.
4. Undo bastard spring that holds in the backing dish in for the headlights. Make no attempt to clean the dish, the dirt will come in handy. Also, don't touch the two adjusting screws, backing dish should just slide out with some gentle persuasion once the spring is removed.
5. Grab one of the new headlights, steal some of the kids plasticine, remove the parking bulb from the new light, and insert round ball of plasticine.
6. Put headlight in backing dish, making sure arrow pointing up aligns with TOP stamped in the backing dish. Remove headlight. Plasticine should leave a round circle on the backing dish where you have to drill a hole for the new park light. Even if the backing dish was clean, the plasticine should leave an oily circle when viewed at the right angle. Mark perimeter of plasticine oil mark. Drill hole, and if required, file with a round file out to the required size.
TIP: If you are using old original lamps with the seperate bulb, there are some issues with the bulb not being in the same location on all lamps. If this is the case, make sure you mark each headlamp separately for each dish, and mark one set so you can maintain the pair. Newer lamps seem to have better quality control and the parkers in the same location.
7. Test fit new headlight and see how you go for fit. By this stage, you should be able to see how you are going for alignment, and adjust accordingly.
8. Nearly there, now for the wiring bit. The park lamp on your old light fitting should be a screw in bulb holder, remove that from the main headlamp fitting. Purple is for positive, and the right hand headlight will have two of them, one coming into the parker, and the other running out to pick up the right hand parker. The other wire, dark grey from memory is the earth. Wire up to new lights with connectors. New aftermarket parkers have different coloured wires but meh.
9. Stick it all back together (reverse process) and you are off.
Hope that helps.

Arrimar, no mate, the bit that the lights actually sit in. Do the new lights you have, have the hole to fit the bulbs in, or the windows that the lights shine through?
Here is a pick of the backing dish that I'm talking about. Note that this is for old HZ H4's, have a separate light that sits in rubber grommets with two straight connectors for the connection. My new ones have a metal sleave, that another metal fitting and spring fits into.
Now, as for the actual standard light fitting, you'll find that the parker bulb actually sits in a separate fitting connected to the bottom of the headlight fitting. This bulb will clip out as it has it's own separate holder. Remove it from the larger headlight electrical connector, cut wires, and wire to suit the lights you have. I'd not be bothering with old headlights. I got new headlights, new Narva (blue) bulbs, and headlight protectors (plastic domes) all for $120ish. New lights come with wires, not electrical connectors, so you need to add your own fittings.
Below is a pic of the backing dish that needs the hole to take the new headlights. It was for the old HZ ones, which don't have holes in the same location, hence the elongated hole. The ones in Ole Yella only have a 12mm hole, as the newer headlights are more consistent with the location of the park light.
Hope this helps. Might help if you take a pic of your headlights, which might help me. Don't go scratching the silver shit off.
Your not doing a square to round conversion are you? If so there are a few extra steps involved in getting it right.

i wonder ,if the parker wires were connected to the headlamp would that work or would there need to be a resistor to lower the power ?
thanks for following me along here.unfortunatly my camera is in under warranty and i have missed being able to record the best bits of building the car.
no the round ones were allready in.

Anyways, have a look, I'm sure you'll see what is happening once you have a look at it.
HZ ones are the ones with the parker light in a slightly random location between different lights/manufacturers.
