Iltis with tailgate 87937 was disposed of out of ASU/CFB Petawawa in November 2005. You are in luck, as I photographed your Iltis at a CFB Petawawa open house in 1988 and I have additional information on this vehicle. It was first used by 3 RCR until April 1986 and then with the Canadian Airborne Regiment until January 1999 when it was transferred to ASU/CFB Petawawa.
This photograph shows it with a M100CDN.
