If your 95 is an auto then you need the one with two cooler ports
4 cooler ports would be a chevy LOL LOL LOL
Seriously none of our explorers use a 4 cooler port radiator, not sure why they list it
If your truck is a 5 speed then you do not need cooler ports
The oil cooler is for the automatic transmission
Your new radiator should come with the correct fittings to thread directly to the trans cooler lines in the truck
If it does not (they usually do?) then you can remove the fittings from your old radiator
You want the DUAL CORE radiator do not get the single core unit, from the factory all 95sgop do not exist automatics came with dual core
