Standard AK pistol grips can be adapted to fit the Vz58 fairly easily, but since the AK has a larger receiver, most of it's stocks couldn't be made to fit without a really kludgey adaptor, nor can anything other than the Magpul Zhukov or some other lengthened forend really be an option.
Of course, there's not much stopping anyone from supplying AK profiled furniture to begin with.
Personally I don't care about the looks, but I prefer the feel and function of AK furniture, especially in not having an annoying crescent shaped buttplate and a more hand filling grip and forend.
