I will tell you right now, information on these vehicles is almost non existent. I sent you a link to the Suzuki mini trucks owners forum, you will have much better luck talking directly with the owners. They know where to get parts, specifications, etc.
Also here is a link to Wikipedia on Suzuki Carry trucks. http://en.wikipedia.org/wiki/Suzuki_Carry
I am sorry but I am being honest, we have dealt with this issue before. Information is very limited.
