Buy Z1 oil cooler kit and paint it blue, lol.
Usual is -10 size stainless steel lines, thermostatic plate, and from the looks of that kit, you will need to create a bracket or you could get a Setrab bracket to fit, I am not sure. I say 19 row minimum for the oil cooler core. If the stainless steel lines are not assembled or specific length, be careful on how you cut them as not to get the ends frayed. The rest
should be plug and play.
BTW, depending on the fitting ends, you may or may not have to use thread sealant (AN vs NPT fittings).
