Possibly going to pickup a 2f from a 60 series with a fresh rebuild on it, 10k miles+/- on the rebuild. Any issues transplanting it in to my 78 40 series? Not sure if the 86 has an oil cooler and my 78 does not. Even though it’s quite the drive I’m considering it since the time money and effort tracking down the parts to rebuild mine seems like a pain. Thanks for any input.
