Gary I cannot help with this one but if you go to -
www.armorama.com/trucks - this is a huge modeling site and if you are not a member join and post this request in the forum there. I can almost guarantee you will have a reply in about 8 hours.
My call sign is MrRoo and I have a hosted forum there for softskin Military vehicles of all types and eras' called 'Truck'orama'. The above link gets you there
hope this helps
