Here you can see the ring drilled with 20 holes that will hold the sender ring mount. I used 1/8" for this one. I cut the donors tank up to retrieve the ring. Not the cleanest approach but it should work.

Here you can see the rear hydro boost I'm using. I used an uncommon hydro boost from a Yukon that has a much larger accumulator. These are used as a reserve to help keep the power brake working in case of engine failure. Just a little extra help just in case....

Here's a better look at the longer accumulators on these hydro boost units.

Here are the master cylinder lines tied together for the rear brakes. The remote master cylinder uses a 37mm piston and the flow should be more than needed for the four rear wheel cylinders.


Here is the fuel cooler mounted. Another necessary accessory for the diesels..

Here is a look at the HB (hydro boost) I will use for the front brakes. It has an adjustable spool valve that can be used to limit front wheel braking pressure. Probably won't need to adjust it but its there and easier than installing a proportioning valve in the brake line.

The HB rod has to be 2.75" for the clutch slave to work correctly. Here I've modified it to the correct length.

Here is the rear HB without the adjustable spool valve.


Here is a good look at the rod ends that have to change.

Another look at the rod on the HB.

I'm using the stock 3.5" muffler to try and keep it as quiet as possible. Used stock to the truck exhaust hangers and will exit exhaust in a new location.

Here is the exhaust pipe installed. A bit hard to see from this angle.
