Hi, built this recently, pretty much straight out the box, its the AMT 1:25 kit, really nice to build. The only extra part was the front bumper, kindly supplied by a fellow brit modeller.The part is US in origin, but not sure who from.
The only really poor part of the kit is the exhaust stacks, somthing which would be better sourced from another kit in this case, or metal items. After I took the pics I notied one of the rear tyres was loose, it can be just about seen, my 3 yr old son decided to take the truck for a push!! luckily it survived ok.
Thanks for looking, Lee
