I modified the Zaku I using the non-revive Char's Zaku II from HGUC as the base! 😁
March 9th is "Zaku Day," so I wanted to make a Zaku I, but I couldn't find one at a good price, so I thought, "Since there's no Zaku I, why not just make one from a Zaku II?" and transformed it!
So the key point is the "modification"!
Below are the construction details and images from different angles.
As mentioned above, the base is the non-revive Char's Zaku II from HGUC.
