Many people are confused about scale and gauge. Many of our products will work in several scales some will not. Examples are water bags, some grab irons etc. as they come in many sizes in rel life.
  Things that are extremely scale specific such as many diecast items. We have many die cast cars that work great in 1:20.3 but are actually 1:18. They work great in 1:20 but not in 1:24.
If you are having problems figuring out a part please write to us, or call us after 4:00 weekdays.
We will be glad to help you. If you order an item that is in the wrong scale you will have to pay shipping both ways to return and exchange it. Remember if you have a question please cal 435-586-1036 after 4:00 weekdays no Saturdays or Sundays  Mountain time
