spark plug gap settings 89 caravan

I have an 89 caravan. I'm cleaning my spark plugs and I think I should probably re-gap them just to make sure they're where they should be. Does anyone know what the plug should be gapped to?

.035

2.2L & 2.5L gap at .035

2.6L gaps at .040

3.0 L gaps at .040

90 and up models 3.3L & 3.8L gaps at .050

thank you much

I did not know it came with a 2.6L. What year was that on. I know that the 3.0L came in the 93 ply. duster.
