Small steps.

The heater core was looped out of the system, but fortunately the heater hoses were left in place. We re-connected them and added about half a gallon of coolant to the system. The heat blows nice and hot. Also of note, the AC clutch turns on w/the little green button on the dash, so we know at least part of the AC is working.

I also got my cable in for the 14cux, and was able to get Rover Gauge (available on github here) up and running. Handy to have the ability to interrogate the ECU, I may look to get it up and running on a tablet or raspberry pi for a more portable solution. You can see here that we're running R3038 - a generic Defender 3.9 tune. I need to sort through all the ECU's we've got around here again and see which ones are socketed, then I can get a tune that is more suited to the 4.6L - there's likely a fair bit of performance left on the table.

All in all - another good day, getting more and more comfortable with this engine at every turn.

As was mentioned earlier - one of the owners of #66 was Woody Woods. Thanks to @Z.G I was able to get a picture of the 110 from his family, as Woody had it on Hawaii. Generally I like this look and think I'll shoot to restore it to Woody spec with a few modern conveniences.

A Long Overdue Update

In June / July - Jim finally took his assignment in Japan. This left me down not only a pair of hands, but a project manager and decades of experience working on Defenders. Over the course of the project, we experienced tons of delays - many related to Covid and other issues. From sourcing a frame to stripping the original frame, to paint and other delays - we just ran out of time. Early last year, Jim and I had Drew at Coniston Classics do the welding on the original frame. The work was great, and while we were at his shop we were able to get a great look at the work he and Jimmy were doing on their custom builds. From the moment we walked into their shop, Jim and I agreed, that should things go awry - and I find myself unable to finish the project, this was the best place we could take it. Jimmy and Drew have a ton of experience with not just Defenders, but Land Rovers in general. They are factory trained LR technicians, and met while they were working at Land Rover ...

Tub Construction

Yesterday Bernie helped me retrieve the rear tub from the painters - between last night and today I was able to get all of the bracing mounted and riveted in place. I'll probably replace a lot of the hardware that mounts the bracing to the floor with some longer - but its good to have things in place. Also ordered a pneumatic rivet gun. Anything else seems to be too much of a headache.

Windows and Rivnuts, oh my!

We've taken a short break from test-fitting the tub to complete some of the supporting bits we'll soon need. I also happened upon the rivnuts required for the Bulkhead and seat box. These are the gull-wing rear windows from Explore Glazing . Hard to believe I ordered these over a year ago. We also fit the rear window into the rear door, which is tinted to match. I also found a source for the oversized M8 rivnuts that are used in the more modern bulkhead and seat boxes. After a bit of searching the McMaster-Carr website, I was able to find Part number 95105A191 , which is listed as a "Steel Twist-Resistant Rivet Nut" " About twice as strong as aluminum rivet nuts, these steel rivet nuts are zinc yellow-chromate plated for corrosion resistance. A ribbed body holds the nut in place so it won't turn when tightening a screw. Also known as blind inserts, they can be installed when you have access to only one side of...
