For 1/35th scale you have these options:
There used to be a conversion set from RealModel for the Italeri M923 or "Bigfoot" to make the M927:
The product number for this set was 35037.
It looks as in PanzerShop
might have one, e-mail him and ask before getting your hopes up [email protected]
The conversion set for the M800 cab (only the cab) is still available:
Italeri base kit + cab conversion + scratch the load bed
or get lucky and use
Italeri base kit + cab conversion + M927 load bed (frame extension, load bed + minor details if I remember correctly).
Are you planning on using the older kits as templates to scratch build rescaled copies in a common scale?
Doing the M814 in 1/35th brings it a little bit closer to the 1/40th Hawk battery ....
Does the Real Model 35037 kit also work on the Italeri M925 kit?
I also found the M800 cab conversion...so I may be getting closer.
