So, these are my coils, have no clue who on here may have sold them to me:
replacement coils

This is the '26 box that "holds" the coils:
old box top
old box bottom

These are the original coils, out of the box for the first time:
original coils

and wires:
original wires

Now a better view of the empty box.
old coil box

There is a metal strap that fell off. No clue where it is supposed to be.
old coil box 2

New parts on the way, some have arrived:
new ignition parts

The plan so far is to test the windings of the replacement coils and if bad, use a good original primary/secondary winding.
Replace all the condensers without even bothering to test them.
Replace all the hardware on the top.
Heat tar in a can and pour.

For the box, a wood kit, contact set, cover gasket, and screws is on order.
I have not seen the DVD videos but have seen some Tube videos and read these threads:

Call me a tight wad, but those nice original wire ends,I glass beaded mine and unsoldered them from the old wires and reused them.:-)
There is a kit available that does not use wood that some folks like. It wont soak up water if it is rained on and leave you tearing it apart trying to dry it out.
I must admit,I made my own wood kit,used a router and such. I made mine out of red cedar. Don't know how well it will hold up long term.
You can clean that coil box using electrolysis to remove the rust.

Arrrgg, woke up in the middle of the night. Might as well respond.
I had no idea those wire ends had any value.
Yes, saw good reviews here about the plastic but I went with wood. I plan on using shellac, inside and out before installing new hardware.
Forgot that I even had a router or I may have tried it. There is cedar in my old truck bed because it is naturally bug and rot resistant. Engine heat would be a new test.
Only thing I'm clueless about on the box is the location of the loose metal strap that rusted off.

That "loose metal strip" goes in the middle of the box from the slot on the backside of the metal, through the front section of the coil box wood. The ends are split to be folded over and help to maintain tension on the coils with their contacts. If you look closely, you can see a rusty piece of it still attached to the back of the box that has rusted in and broken off. Doesn't look to be in very good shape however, and that's one of those items the vendors don't offer as a replacement.

Ok, just so you know where all the bits and pieces go, I thought I'd post these two for you.

I got this coil with 4 I bought from eBay. That's always a gamble. Picture just showed 4 in the box. When I got them this one was missing the capacitor and the side that is missing, that's not the side that is supposed to come off. I put a new condenser and points and it works. I need to make a side and find a glass insulator and some tar I guess. It's a lot worse than the picture shows but I figured I'd try it anyway.

Vern, I've got a couple spare 26/27 coil boxes in much better shape than yours. If you are interested in one of them send me a message.

The coils in the box that fell apart.. are better than the coils i'm rebuilding now. Mine have worse wood and have been underwater for a year.

Naked coils!
I can't stand the excitement!

I need to take a cold shower.
It would be a warm shower but I am trying to save for a new radiator.

Awesome guys, thanks for the responses.
Kevin, I found the strap you are talking about 5002STP at Big L and bought one. It keeps the wood from bowing outward. The strap that I was referring to I finally located near the bottom of the box.
Thanks John for offering to help.
coil box strap

I did not see the 5 screws listed: but would like to buy some. They maybe look like #10-32 carriage bolts? brass? Could use a link to purchase or confirmation of size to acquire at hardware store. Part#?
coil top screws

Corey, I have not opened the replacements but I already have new capacitors. The little nail has beat me so far.
Wow kep.
Martin, thanks. Best drawing I have seen to far.
Vern

Vern, do yourself a favor and re-wood the coil box with John Regan's that (you can either get from Regan or Lang's) 5000-5001RKB, it'll make your coil box moisture proof. And be sure to get the 5001BCONBQ contacts as well, they don't get squished even over time. :-)

Corey
When I rebuild coils, I remove the glass insulator. The is no need for it.
