My view is that the two shaped washers are there to accommodate lateral movement of the lower kingpin mount to achieve desired camber via the camber plate adjuster on later models with this adjustment. The washers allow the kingpin oiler bolt to tighten down squarely through a small range of angles. This can only happen accurately if the two washers are immediately under the bolt with their shaped surfaces facing in to each other and so working together.
My factory fitted reaction bars were mounted thus concurring with the image shown in Cains instructions. Mounting the reaction bars above the washers makes a farce of the provision of such washers despite seemingly something you can get away with.
As a side note if the reaction bar is mounted lower at the top, the point at which it interfaces with the chassis would be further back. Wouldn't this reduce the likelihood of tyre touching same on full lock?
