Looks good Steve. You're going to have a busy day ;).  I have also found some cracks, mostly at bolt holes.  I have also found some parts that had numbers stamped from other halftracks.

Been busy the past week. The dash and windshield frame are both repaired and painted.







I did get the PTO mounted back on the transmission and decided to fill with gear oil. I tried using a pail pump from Harbor Freight. That was a bust as the tubing ruptured and oil went everywhere. There are some things not to get at harbor Freight and this is one of them. 



I ended up taking that back and getting a better hand pump at a farm store. I will be using this today.



Got more parts painted and now running out of space to store the finished parts.





Now the fun part. I get to put stuff back together. I reassembled the floor vents and the radiator armor. One louver is missing as I needed to do some body work on it. It was very pitted so some body filler was used and will be painted today.





Starting to get parts laid out to do back on the dash and firewall.





As far as the ignition system goes I'm making a few changes for the better I think. All this stems from my experience with old Chevy trucks. I still have my 1951 Chevy that I need to finish some day. here is my list of changes.

1.   Add a pertronix unit to replace the points and condenser. This was done several years ago and works great.



2    Add a multi spark ignition module. This will be hidden in the original coil box. this will give multiple sparks per cycle instead of just one. it should help starting, idling and prevent plugs from fouling.



3.   Add a vacuum advance unit to the distributor. This is a factory bolt on item that Chevy used on its six cylinder engines using a similar distributor. I only need to machine an 1/8" from the base.
4.    Change the air cleaner to the paper element.
5.   This next item came with my halftrack. A Marvel Mystery Oil Inverse Oiler. This devise put the correct amount of Marvel Mystery Oil into the intake manifold and lubes the valves and keeps things running good.

The one change I had made a while back, adding an electric fuel pump, I'm changing back to original. This is so I can use my windshield wipers. I may add a vacuum reservoir.

That's about all I have to report for now. More to come.

It looks like you're moving along pretty good. It's time to put some parts back on and make some room in the shop ;D. I like the electronic ignition, I may upgrade mine in the future.

Making some slow progress but it is great to start putting things back together again. Here are some photos of my recent progress.







Starting on wiring the dash. What a project that is. Glad I got a lot of reference material and diagrams for this.

Well, it's been a while since my last post. I've been having difficulty with my health lately. Anyway, I finally was able to get some work done on my halftrack. I have since finished my dash and installed it back in the cowling.





Here, I'm working on the finishing touches on the firewall. The horns were sent out and professionally rebuilt with all new internal parts.



I finished hooking up all the brake lines and master cylinder.



Re-installed the e-brake assembly. Now waiting on getting the e-brake and PTO levers cleaned to re-install.



Thanks to Kevin put all new hose clamps on and connected all cooling lines.



More to follow.

I'm still plugging away on the firewall and dash. It's amazing how fast it is to take one of these machines apart and how slow it is putting it back together getting all the gingerbread details just right. Anyway, I had another slow down in my work. Kidney stones, I don't recommend them. They are not fun. I'm feeling a bit better now. Got some parts re plated and look great.



I didn't want to paint them. They look better plated. I hope to be ready to install this onto the halftrack by sometime next month. Enjoy.
