I did see your ad a while back which made me decide to get one at some point. I managed to get a deal on a small lot of parts that included a cooler but no fittings, Ts or Ys. Mine has a partial stainless braided flex line though that connects to the forward oil connection. Thanks(!!!) for the picture of the block fitting, makes sense, I will see if I can get one used or from MBCC.
