Adding interior to a Merkur passenger car

Today I visited Blik & Speelgoed and purchased a passenger car interior (8961) for Merkur passenger car 9330. Under an unforgiving hot sun, we went home and assembled the interior after sunset in slightly better temperatures.

Here are the two parts prior to the merger.

Unscrewing six screws and the roof was removed. This clarified that I had to unscrew another six nuts for retaining the interior. This flexible metal interior was fairly difficult to get inside, so I loosened another 5 nuts to loosen a side panel and then the interior flipped into place. So, then I had to tighten the nuts of the side panel again.

Then the six screws and nuts through the bottom plate and the interior and then the lot was secured.

So, finally the passengers are able to sit down and relax. So, after this close encounter with all them nuts, screws and washers, I do know that these Merkur cars are decently constructed and making modification is fairly straightforward.
