Gettin' there, folks!
First, windscreen had to be made from scratch, since the windscreen frame was significantly widened from the Revell Classic VW kit. Thankfully, it's flat, so, not impossible. Started with the original windscreen, traced it, then added the appropriate fill plug, on paper. Then, cut the new shape from packaging from something-or-other that my lovely wife bought (no idea what, it was in the recycling).
Next, the bumpers. Closest option of the 3 kits is the Aoshima, except these represent the slightly later style with embedded lights.
Removed the chrome with bleach, grind off the rubber strip (too wide), fill the light slots, add a new rubber strip. Prime, spray black, mask the rubber strip and spray Alclad chrome.
