new thermostat housing and temp gauge

So I decided I needed a better water temp gauge on the fox. After looking at prices options and new sensor locations, I decided on a super cheap digital gauge and a new thermostat housing with a 3/8 port. The first gauge I received was in Celsius which I returned and ordered a 3/8 to 1/8 npt adapter.
I found an AutoZone thermostat housing combo with a gasket. 
There was a good amount of casting slag in the turn of the water neck which I took a file to. 
I didn't notice the waterpump bypass nipple was an inch longer than one making getting the tiny right angle bypass hose on and real pain. I ended up folding it in half and ziptieing it, to get it started on both nipples at the same time. I found some corrosion on the threads of the bolts when I took it apart so I coated those in liquid ptfe sealant as well as the sensor and adapter.
For a gauge mount I am just using some scrap plastic and a 2" hole saw to make a temp mount. I'd like to make a dash pod that sits where the old autometer tach is currently.
I also need to add some foam to an area of the fan shroud I trimmed to fit the previous radiator.

(Update, I am embarrassed to say the old thermostat was installed backwards. After correcting this with the new water neck, I still need the wire in the new gauge but honestly it runs half or below on the gauge even in traffic, at a dead stop the fans pull from the alternator but have not caused a stall just a dip in rpm)

Flywheel, clutch, bell housing and some other details

Image
Installed the new flywheel.  Installed the new clutch.  Installed the clutch fork and throw out bearing  And then the bell housing  Installed a new transmission tailshaft seal.  I built a sled to drag it into place under the car and there's a bolt that fits the center of my jack through the center board. I may have to pull the shift cause there's exactly 19 inches under the pinch weld and thats the same to the shifter nub.

power steering rack line seals

Image
I finally decided to stop the leak that leaves a ton of fluid on my garage floor. I ordered the maximum motorsports rack seal kit. The instructions say you need to be clean before applying the sealant to the threads. I drained the rack and purged the rack after the lines were off so I could get rid of that little bit of fluid in the ports. i decided to completely remove and flush the lines to install the nylon seals. And have them stay clean through the install. the old one was chewed and the one that looks like new, wasn't installed right. Used the 2 screw driver method to gently stretch the rings out.  Then of course I take a break and get COVID. So 2 days later I am posting the pics.

water pump redo

Image
So with the change in temperature at the beginning of the year the water pump started sleeping when it was cold. This gradually got worse through the heat cycles. With corrosion evident on the bottom of the pump I decided to redo the water pump even though I am sure it could have just been resealed and been ok. I think I made 3 mistakes last time. I used the crap black gaskets that came with the pump. I used ultra grey rtv. I sealed the inner air pockets inside the pump. These filled with fluid and with the thermal expansion compromised the gasket. I went for a motorcraft pump this time as well as the light blue permatex rtv 22071. After I heatcycle the motor a few times I am going to go back and torque everything again. I also replaced the 2 left bolts that had corrosion on the from last time, with stainless ones. (5/16 - 18 4") I would have liked a 3 7/8" bolt but it's not available in stainless locally. I put a cut in an old bolt and chased the ...
