Thanks. I will try.
A. the description was found in Angelucci's book 'Modern Armour' I think it was also in Jane's for the late 1980's but I don't have those. It's hard to see how it could be written unless someone had seen drawings.
B. the picture came from a Japanese website. The machine translation on it referred to 40 tons, front engine, acute angle armour and 105mm rifle or 120mm smooth bore. I have a downloaded page but the pictures there won't show - except by opening the files to get at the gif, which is what I hope follows. I do not have a url for it.
PS forgive the typo for Lamborghini
