Conversation Between 72f2504x4390 and damac

I was just wondering for which car you serviced your oil cooler? I am searching every diesel forum I can find because I believe I need to do it on my 1985 f250 supercab 4x4 with a 6.9

I am having the problem now of making sure mine is the same as other posts I come across and to get the proper replacement parts

thanks for any info!
