trans cooler mounted to frame connector, Duster

Currently my Duster has the stock trans cooler lines up to the radiator. It's connected to rubber lines that go under the rad support to an aux. trans cooler zip tied to the radiator. These are just regular rubber lines with hose clamps. Naturally, they are leaking.

Here's my question - anyone mount one of those dual-pass, aluminum, finned 'heat sink' type of coolers to their frame connectors? Like this.

This way, I can get rid of the stock, car-length lines and not have to mess with fitting things around the rad support to mount the cooler properly.

Also, please confirm that the cooler taps on a 904 case are 1/8" NPT.

Pics would be great!
