I hope this is not a repost.
I found this Mr.Akira Watanabe's blog, He is a person who knows well about Isuzu in US and Japan. He writes a lot about Bellett, Chevrolet LUV even Unicab and Trooper.
This is his profile page :http://www10.ocn.ne.jp/~awjuno/sub4e.html
He said that in 1984-1988 he is Member ｏｆ ｔｈｅ Board, of Isuzu Motors Co. Inc,Director in charge of R&D of light duty vehicles
and in 1988-1991 President, Isuzu Technical Center of America Inc.
This is his main page about automobile :http://www10.ocn.ne.jp/~awjuno/sub600.html
It's in Japanese, but you can read the translation from here :http://id.babelfish.yahoo.com/translate ... erjemahkan
The translation is not good, perhaps someone in this site can help to translate it.
I cant upload pictures right now. But I've upload some of them in luvtruck.com, bellett.net and isuzupup.com
