Now that the car is back, I felt the need to go out there and do something, even if it is something small. Keeping in mind that I will be doing a lot of wiring under the dash, a removable steering wheel hub seemed like a good idea. My friend Tom had a NRG steering wheel hub on his 70 GTO and I really liked it.

I started by removing the horn button and removing the Momo steering wheel from the Momo hub.



Then I removed the nut that was holding the hub in place.



I had to use a 3 jaw puller to get the hub off the steering shaft.



This is the Momo adapter hub for a GM steering column. If anyone needs it, PM me.



This is the new NRG hub. None of these parts came with any instructions. I am not exactly sure why the hub has a ground wire on it...



This is the hub that bolts to the steering wheel and snaps on the receiver that is bolted to the steering shaft.



This is the finishd column with the receiver hub bolted to it.



To release the steering wheel from the column, the ring under the steering wheel is pulled back...



and the steering wheel comes off, along with the hub.



It will be a lot easier to work under the dash without the steering wheel in the way and it adds a small level of theft protection to the whole car.

Fantastic work on the exhaust. Good luck making September, Andrew.

With the car now in my home garage I am able to spend a hour or two here and there and knock out little projects. Just like the old saying about how one might eat an elephant...

This picture is at a little bit of an odd angle, but it shows the finished turbo drain. While the car was at Hotrod Express, I asked Josh to put a bead in the 5/8" stainless tube that we used to extend the drain pipe. There is also a little section of 5/8" oil safe rubber hose that goes from the tube to the oil drain on the side of the oil pan. I used Gates heat shrink clamps on the hose. The stainless tube also has a silicone/fiberglass fire shield over it.



This picture is also at a bit of an odd angle, but it shows how the heater hoses come down from the water pump and under the up-pipe. There is fire sleeving over the top of the hose where it passes closest to the up-pipe.



Here is the view from the top. Everything fits very closely together, but there is just enough room to turn fasteners and fittings. I also used the Gates heat shrink clamps on the heater hoses.



I took the intake off again so that I can clean everything and get it ready for Cerakote. Here I am mocking up the little silicone plugs that I will use to seal off machined and tapped holes.



She is looking more apart than before, but progress is being made.

I have been watching the weather forecast, looking for a partly sunny day, with low wind and no rain. Well, today was that perfect day. I got started in the morning and started my Cerakote shop.



I had 4 parts to coat: compressor housing, charge pipe, intake lid and intake base (not pictured).



This guy was super helpful for cleaning. I filled it up with acetone, pressurized the can, and it sprayed a beautiful, fine mist that cleaned the parts well. Everything was already bead blasted before hand. I just sprayed everything down, used a red 3M pad to clean, and sprayed again. Then I used a MAP gas torch to heat the parts and evaporate all of the acetone.



I am using the Cerakite C coating, in the same burnt bronze color that I used on the valley cover and the front cover. You put down a light coat and immediately go over it with a heavier coat. It looks amazing in the sun, because the burnt bronze has a ton of gold and copper flakes in it.



I decided to leave the intercooler in raw aluminum, but I went over all of the surfaces with the red 3M pad to give it a brushed look.



I taped off the plate with my business logo, so it would stay natural. The engraving would lose all the detail if I was to paint it.



I set everything back on the engine so that the Cerakote can fully cure.



Different angle...



Here is a shot showing the compressor housing.



I did not mess around with the charge pipe because I want it to fully cure. Now, if I can only find all of the o-rings that I need to finally assemble everything....

Looks nice Andrew.

[SSLance]

Looking good Andrew! Final stretches now...

Very nice Andrew!! I love the bronze color on stuff...wheels, brake calipers, engine parts, you name it.

[WSSix]

Agreed, the bronze is a great color choice.

I have ben working with The DriveShaft Shop for about 15 years on various projects. They were the ones that made the custom axles for my RX7 when installed a Ford Cobra Mustang rear diff in it. They were also the ones that made the single CV driveshaft for my GTO back in 2013 and also the dual CV driveshaft in the Cougar.

This time around they will be building a dual CV driveshaft for the GTO, but with a twist. They have some new, super strong CVs that they want to use on this project. The front slip yoke is already configured for it, but the rear needs an adapter, because the CV pinion yoke was made for the smaller CV. That said, they designed an adapter for me and sent me a 3D printed prototype for test fitting.















We live in truly amazing times. As Vic likes to say "That's some Buck Rogers S**t!"
