I'll try to get the mount to the V bar in here at some point but for now, this will be assuming the Setrab is in the grill mounted to the V-bar low enough to get the extruded fin steering cooler above it.
The 42RLE cooler line ports are generally upper and lower. The lower is the out to the radiator and it goes to the right side. Not a big deal but it also means that the cooler lines added for the Setrab will cross over each other.
Routing-
Out (lower port which is also lower hard line) from transmission to the radiator cooler on the right side. This one is left alone.
Out from radiator return port on the left side is routed to the inlet on the Setrab on the right side which is also the lower port on the Setrab.
Out from Setrab upper on the left side to the return hard line back to the transmission upper port.
The only adapter I have found for the cooler port in the radiator is the one made by ICT Billet for the 05-06 quick disconnect style.
I have yet to find anything good to adapt the 03-04 so we custom make them.
It is used to convert the left side radiator port to -6 AN Male.
There are several ways to attach the out, I like and use AN stuff, they do make a push on adapter but the steel versions are very expensive. Hayden makes brass ones, I'm not a fan.
There are also a few options to attach to the return line back to the transmission, I do it two ways, most common is to split the crimp sleeve with a cut off wheel taking care not to get into the hard line and remove the rubber hose there.

I make a nice little stainless steel tube fitting that is -6 male on one end, -6 female on the other that is long enough to get out of the radiator easily. This assumes you have or will convert the ports on the Setrab to AN male in -6. The cooler has 22mm ORB or o-ring boss ports, the Setrab adapters are too expensive so I have some from Racetronix I use.
When the SS tube fitting is installed, it looks like this-
We hole saw the rubber air dam to make it easier.

Finished routing at the radiator. We also drill the fan shroud on either side of the top line and use that for some good zip ties to hold the lines in place and keep them out of trouble.
This is the push on method with 2 Oetiker clamps. The other method is to cut the factory barbed end off and use a compression to -6 male. They are about 15 bucks each in steel so we tend to lean more towards using the clamps.
The plastic hose clamp to an oil pan stud on this one was still intact so we just made sure it would stay in place with a couple of zip ties.
A few notes-
The Setrab bolt bosses are delicate. They will also let a longer bolt punch through into the cooling tubes, don't do that.
The cooler is fairly delicate so when you tighten the adapter fittings, you must use a back up wrench. We install them with red Loctite so when you removing the female fittings off of them, you don't turn the adapter fitting and cause a problem or a leak.
This is mostly a pictorial reference of one way to do this with stuff I've figured out after doing many of them. This is not the only way or perhaps even the best way, it is just easy for us.
