Most of the details offered by Eduard are an inprovement to the stock, plastic parts, but I must agree with you that does not always include the instument panels.
Sometimes they work, but most of the times I use decals (Eduard or Airscale) with seperate pe-bezels from differant sources.
That gives me better detailed gauges with easy to paint rims, works just fine.
I just wish that Yahu models would do a series of WW! instrument panels, I have several of them for wwii kits and they are miles ahead of the Eduard ones... I have asked them, but so far no aswers.
