I'm glad you appreciate the history associated with the car and plan to preserve its patina.
I'm quite happy to help satisfy your request here Andy. I'll only warn you that there isn't a whole lot of period content of the LARK GTRs floating around. This is partially due to their limited race careers, but certainly has more to do with the challenges of finding good historical content through Japanese websites.
In fact, right now I have more photos of #13R that were taken since you became its owner than I do of the car when it was actually racing and very few offer the type of quality you'd want to use to print a book with.
I have seen some Japanese magazines that covered the 1996 Japan GT series in my Yahoo Auctions Japan searching, however I don't have copies of any of them in my collection to even offer scans from.
I've always said this forum is in desperate need of a Japanese enthusiast to help cover that portion of the world and it's definitely true in this instance.
