Using the Tamiya 1/35 model, which of the versions depicted must I choose for an East German T-55A? I'm thinking about the options C or D, but I'm not sure.

Another thing: will the Eduard PE engine covers be enough to "NVAise" the T-55 or do I really need the Blast set with the different engine deck and cupolas?

I already have the CMK interior set and the TL decals. I'm also thinking about getting new tracks and barrel, but this kit is getting expensive as it is
