'95 K2500 6.5 TD/4L80E
I am wanting to remove an OEM 48 plate cooler and replace with an OEM 72 plate cooler, but it appears the lines are different, unless I am looking at this thing wrong. The new cooler (72) has 1/4" NPT threads going into it. However, I am not sure what size the lines are on the existing cooler. They seem to have some sort of bushing with a spring clip on it before threading up into the cooler body.
anyone had one of these apart before that can tell me what all the thread sizes are? I am trying to avoid cutting any lines and would like to maintain factory appearance and reliability of the steel lines full length.
Thanks in advance, Snowman
