Looking for a set of 4. I can only seem to find the ones with the tab on each end to fit a 4 row radiator. All the ones for a 3 row have a mounting tab on the bottom. Anyone know where to find the ones I am searching for?

 

3 row and 4 row isolators are the same design....with the 4 row isolators being a bit longer compared to the 3 row.

Your question isn't very clear. Fusick Automotive and Inline Tube should have both types of isolators......for 3 row and for 4 row.

You may be seeing pics showing the 4 row isolators with the 90 degree bend on each end MOLDED INTO the isolators.....while the 3 row isolators may not have the90 degree bends molded in (ie- they appear to be "flat' or straight).....you just bend the flexible 3 row isolators when installing them into the metal saddles on the top plate and lower radiator support.

 

Here are 3 row isolators from Inline Tube---90 degree bends are already molded into the rubber

The "3 row" you were seeing may have been the more common Chevy design where there's a retaining tab right in the middle. At least I think it's Chevy. Anyway, the Olds 3 and 4 row, like Patton said, use little nubs on each end that go through small holes in the bracket.
