Matt,
You also need the larger supercharger intake for the Jumo 213F engine. I don't know if anyone produces a conversion in 1/32 at this point. I thought if anyone did, Eagle Parts would, but their 1/32 updates are strictly for the D-9.
All,
I've made some more progress on Red 3. Something snapped in my head tonight, so I went ahead and painted both Red 3 and Red 13. Red 3 came out beautifully, but I royally screwed up Red 13 and had to strip off the paint and start again. Of course, the wings have not yet been permanently mated to their fuselages, but that'll happen after I get the engine plugs. Red 3 is completely camouflaged in an 82/83 mottle over Grunblau (sometimes erroneously known as RLM84) with the RLM23 red undersides now. Next step will be to seal it with Future, hit it with a sludge wash to bring out the panels, etc, seal that, and then decal.
