I got few emails asking for more on conversion-made-easy.
For now, let's start with something simple.
Some pointers to convert the Escort RS1800 into the one that been driven by Droogmans in 1981 Rallye Haspengouw. The conversion is done based on Reji's 1981 Rallye Skoda decal, which to me is the more common in the market.
Of course you need to have two things first. A base car and that decal
Here are some reference photos
Best of luck
