oil cooler lines

Hey guys, looking to upgrade the look of the oil lines going into the oil cooler from the engine to braided stainless steel with red hose fittings. What size fittings should i be looking for? Also, the fitting going into the engine seems different...looks like there are bolts holding it on. Can someone point me in the right direction with this?

I have been looking to upgrade my 84 GPz550 lines too. Haven't found the correct bolt on fitting to the oil pan. I was thinking of having a machinist fabricate new bolt on and adapter.

The guys on the turbo site have been bringing them to a hydraulic shop and having them put new lines on the original fittings . Seems to work good .Not sure about colors .
