3.0L omc plug wires

[tbrooks1015]

I need to replace plug wires, but I'm unsure if i have delco est ignition. Motor isn't original and I believe the original owner had it changed to it but I cant remember as it was about 5 years ago. I dont want to take it apart and im not finding any part numberson the distributor anywhere. Is there an easy way to tell and does it even matter? I was looking at Sierra part # 18-8833-1 and 18-8800-1

The EST distributor uses post type connections and are different then the leads which go inside the cap. EST has 2 connectors on the side

Thanks for the help AllDodge. I ended figuring it out late last night. Its the EST. Upon further inspection its time for a new cap and rotor as well.
