Kra'vak tanks in 25 mm and 6 mm

I'm looking for information on tanks for a Kra'vak force. I was looking at the
Stan Johansen Miniatures tank parts in the Accessories section for 25 mm. The
ability to asemble my own is probly as close as I'll come to Kra'vak tanks.
How do these look next to the Kra'vak figures? Also, are ther any pictures of
the Kra'vak Dirtside vehicals? Ground Zero
Games Online Catalogue at http://www.lightspeed.u-net.com/gzg/index.html
only has half of them Pictured and does not show any idea of size. Right now I
am assuming these classes and using these as substitutes:

 DF-K01 Ha'Iv light grav tank
Class 3 Triton IV
 DF-K02 Ki'Ca heavy grav tank
Class 5 Ganymede
 DF-K03 Ki'Vas AA grav tank
Class 3 Triton Defender
 DF-K04 Tu'Ha grav light infantry combat vehicle                Class 3
       Triton IFV
 DF-K05 Ko'Ta attack VTOL craft
Class 3         Aries AV-55
 DF-K06 Ko'Iv scout VTOL
       Class 2         Pisces SV-68
 DF-K07 Ka'Ha Grav Heavy Infantry Combat Vehicle        ???
       ?????
 DF-K08 Ki'Rok Grav Heavy Strike Vehicle                        Class 4
       Deimos
 DF-K09 Ko'Sha Heavy Aerospace Combat Craft             Class 3
BattleTech "Flying Wing"
 DF-K10 Ki'Sho Grav Artillery Vehicle
Class 3 Helltor

Are these correct or should I modify them? Does Geo Hex, or whoever gets the
molds, have any plans on bringing these tanks to North America?
