This helps narrow it down.
What the guy with the jeep has is either rain gutter towers

or Q Towers with Q clips that fit,
But based on what you said before it sounds like he has rain gutter towers which will not work with your 97 4runner.
Final Question: Do you have a factory rack on the 97? This can be bars/plastic running the length of the truck, doesn't have to be the bars running across the width of the truck. If you look at the top of your 4R, if you have some sort of rack up there, even if it is flush to the top of the truck, you should see channels in them. If you have these "channels"
What you need is the "Control Towers" with 2 sets of "Landing Pads #1" Think of the landing pads as the base of the Control towers, this is what custom fits it to your truck. Here is a photo of what I mean. I noticed on the website you have linked they do not have the landing pads, but you will need those to make the Control Towers fit your 4R.
If you have absolutely no factory channels or rack on top and it is smooth you will need Q Towers (4 pack) and Q Clips #62 (2 sets of 2)
If you take a picture of the top of your truck I will know for sure. If you do have two cross racks going the width of the truck there are the options involving might mounts I talked about before. but your better off getting towers, they can hold more weight and you can use the 66" bars to make sure you can fit the kayaks on top. If you have some sort of channel on top the Control towers are the way you go.
You can usually find used Yakima supplies on eBay, also they are onsale at REI.com
