Oil cooler question
 

I know we mashed over the oil cooler issue a while back, but I have come across an unusual finding or so I think it is. My 91 GTA oil cooler pipes are getting ratty. So I was going to switch them out for the ones on the motor I took out of my brothers wrecked 92 Camaro because they are aluminum. The following is what I found and I am wondering if it is stock.

Notice the lack of rubber lines!

The 1LE Camaro's had oil coolers from the factory.
