Yes, similar body mass as well. Showa Mechagodzilla's height stands out a bit more than Kiryu or Gigan, as can be seen on the Godzilla vs. Titanosaurus box, but otherwise works well too.
And let me tell you guys, "completing" my six-inch Gigan collection has taken far longer than it ever should have. Technically, I still need the half-ruined Bandai Creation version, but otherwise I've got the significant variations thanks to this:

Light blue, green, and now black. Ok, not the
most exciting pickup, but it is my first 50th Memorial Box pickup, and at a great price given the rarity of the set and its current secondary value! Most of the black Gigans I've seen in the past easily go for $20 or $30 before shipping, so this worked out to my satisfaction.
If I could get the others at a similar price (well, minus flat-out reissues like Ghidorah or '54), I'd be paying as much as or less than others did for the whole set originally. Sadly, I think most of shado-x's auctions this time were flukes. Or maybe his lack of PayPal drove bidders away?
