HOW TO UPGRAGE TO SQUARE HEADLIGHTS
Twin square are pretty straight forward. I did mine the other week in about 2 hours and I'm an electrical numpty. However I am a military aircraft fitter by trade and have a cheap Lidl soldering iron
I bought the correct lower mounting brackets (seen below) from VW 255-853-647 x 2

Then to fit you need to gently bend back the two outer mountings on the Van with a hide mallet or something. not quite 90 degrees back should do it (that way you can bend them back if you ever go back to round headlights). They are the outer 2 of the 3 tabs that the grill is secured to, as they get in the way of the square light assemblies and you don't need them for the square grill.
Screw the VW mounting tabs onto the lower inner corners of each lamp assembly so that the are orientated as in the picture above
The two outer upper and lower screw holes on each side are used to attach the square lights. So screw the light fittings to these two holes then mark where to drill the upper inner hole and the two lower holes for the mounting tabs.
Remove light assemblies and drill holes approx 3 to 3.2mm (I used 4mm tamper proof self tappers). Be carefull not to damage your paintwork or any wiring looms as you break through.
Rivet the mounting tabs to the body. Again watch the paintwork.
I am assuming you got the wiring looms with the headlights?
Leave your existing side light wires alone you can use these
Snip off your existing headlight connectors about 3 inches back from the plastic connector block
Now solder and heat-shrink the wiring looms you got with the square headlights to your existing loom matching up the wire colours on each side. Ignore the side light block on the loom. Tie wrap this up neatly out of the way and maybe tape up the socket to prevent any water getting in.
Fit headlights to body remembering to plug them in first.
Fit square grill
Ring local MOT place to get the lights re-aligned
Stand back and admire.
As promised here's some pictures
