Howdy, Doug!
Why not use alias items - link the make and model to the item code, then they could simply select it, then it shows on the order/pick ticket/invoice.
You may want to add a script if the item is selected to have them select from the alias table. And when that make and model is no longer available, you simply delete it from the alias table.
