Help with Hastings rings

Trying to figure out which way is up on a set of Hastings rings for my 74 850.
If I look at the profile of the compression rings there is a bevel on the inside diameter. In the picture it looks like the wider part should be the top with the bevel down. However the picture shows a slight dimple in the top of the ring. I can barely make out the dimples but they appear to be on the narrower beveled side of the rings.
Any help would be appreciated.

Thanks LAB, much clearer pictures on the website than on the instructions included with the rings. Was able to cross reference the type ring and determine it is a type 102 normal torsional, then go back and find the correct picture.
