I guess this is the problem trying to get these US made parts intended for an AK to fit a Vz58. I thought it was going to be a bit more painless than this. I really like the look of that Zhukov folding buttstock, but the fore-end I can take it or leave it. I think I might go for another brand fore-end. I don't want to mention the other brand here, as I'm respecting CTCS's forum, and I don't think they sell them, but there is a brand made
FOR the Vz58, by an ally, in the mideast

,... which already fits. I had hoped this Magpul Zhukov set would slip in a bit easier without so much tinkering. I didn't realize the 2 chassis's, AK vs Vz58, were that different, but I'm a newb to them both, so I blame my ignorance and over-optimism. I guess I was confusing the compatibility of the CZ858 stuff versus this AK furniture with fitting a Vz58,... mistake on my part.
For the tinkerer's out there that's great, but this Magpul price isn't cheap enough for me to warrant the time needed to spend on getting the fore-end to fit. I think the buttstock likely requires less work than the fore-end so I may go for one of those.
Good effort by mattcwc, but I'll be watching from the sidelines now only, cheering you on. ;-D
