I too would love to upgrade the front end of the express to the starwagon lights/grille
for the newer more modern looking starwagon lights...
from what I've seen from looking around, you'de basically need a whole starwagon front end, the whole nose from the bottom of the windscreen to the top of the bumper would be needed to swap lights, and a bit of rewiring would be needed for the separate high & low beam lights, and the relocated indicators on the bumper.
as for the rims... I run 16x7 +38 on the front and 16x8 +32 on the rear, sits very nicely, I've also lowered the van 50mm
