Not quite ready to try the electric steering?

Definitely let us know how you like it, Andrew. I've heard good things from people who have put them in their C10s. I've considered it even though the truck isn't a performance build.

The cover plate came out looking good. I hope the electric booster works well for you.

I am pretty excited about the iBooster. I haven't had power brakes on this car since it had the original brakes on it.

Before the next update, I want to send a shout out to a great vendor. It is not often that a company surpasses my expectations, but Stainless Bros definitely has.

This is how they packaged one half of the 4" v-band clams that I received from them.



Each v-band was in it's own box and the clamp itself was in its own sealed bag.



The v-bands themselves are like jewelry. Each half indexes into the other, which is a great feature that makes it easier to align the pipes.



I was also able to make it out to my local Napa store and picked up a roll of 5/16" butyl tape. I used it so seal the back of the close-out panel that I made the other day.



I was also able to use the boot that came from DSE. This is a boot they use with their low angle vacuum assisted booster.



Once the iBooster is installed the plate isn't really visible.




I also started on the new brake lines. I am using 3/16" NiCopp for the front brakes and 1/4" NiCopp for the rear brakes. The 12mm flare to AN adapters are from Earl's. I am not really happy with how far they stick out, but I am not sure what there is to do about it.



I also got this Cummins turbo drain as a starting point for my drain. More on that in a future update.

I've been using their pipe for my project. Nicest looking stainless tubing and bends I've found.

Cover plate came out really nice. Car is definitely coming along.

Curious why you didn't use a flare nut on the line, that would thread directly into the master instead of an adapter?

Good question...I don't know that I have a good answer. I think it was because the MC fittings would have made it hard to use 3/16" tube. It made sense at the time...

I spent a little time at Vic's today working on various odds and ends.

This is a clever little part from Motion Raceworks. It's an oil inlet block that bolts to the top of the oil feed hole and seals with an o-ring. It then points the oil feed line straight out the side. This will connect to the oil feed line, which at the moment terminates at the front of the passenger side head.



A few days back Vic also made this fantastic mount for the Dominator ECU. It bolts in place of the glove box and will allow me easy access to the ECU connectors. Ignore the duct tape. I will be placing an order with Vintage Air soon to clean up the under-dash ducting in anticipation of having working AC in the car.



I also brought the shifter to see how it might fit inside the car. In the picture I have it sitting over the hole where my manual shifter was located. It is slightly offset to the driver's side. I am not really sure about the shifter placement yet.



Vic worked out the final placement of the waste gate and started on the fabrication of the needed plumbing.



It should have good priority flow in this location and provide an easy path to route the exhaust from the waste gate back into the downpipe.

Finally I can say I did a few things on the car, mostly by myself...LOL

Yesterday I received the last few parts that I needed to finish the new brake lines from the MC to the distribution block.



I also welded on this oil drain tube. Vic made a couple of adapters on the lathe and I welded it together. The welds are horrible, but it should hold. Because of how everything is situated, the drain has to take a slight jog to the passenger side immediately after coming out of the turbo. This is a turbo drain for a Cummins something or other. It is fairly flexible and is made out of stainless steel, so it is relatively easy to work with.



Once it makes the jog to the left is has to sweep right, under the up-pipe and under the exhaust manifold, then towards the drain in the side of the oil pan. I will extend this tube so it is all metal under the hottest pipes and there will be a short section of hose connecting the drain to the oil pan.



The waste gate discharge is tacked to the downpipe.



The downpipe itself is also tacked in place.



There is also a 4" v-band at the end of the downpipe that connects to this pipe that shoots the exhaust straight back.



I am not sure yet what's going to happen with the exhaust once it is past the transmission crossmember.
