Well the firewall is all buttoned up. I filled 45 holes. About 20 small holes, 20 quarter size holes, and five large holes. It is not perfect but I am pleased with how it turned out. With a little sanding and a light coat of filler it could be great. The best compliment I got was from my wife who didn't believe it was our car when she saw the completed picture below. Thank goodness old metal is thick otherwise I could have never patched the firewall with my inexpensive flux core welder.

Well, I haven't posted in a while although I have been doing some work on the Caddy. I have been on hold due to waiting on a fuel tank. It is a tanks brand universal tank but everywhere was out of stock and Tanks was waiting for some to come in. Well, long story short I finally got a tank 3 months after I ordered it BUT only because it has some minor damage. Actually, they told me it had a dent around the sending unit and that they were worried it wouldn't seal. I got it yesterday and I can't find any such dent and it looks as if it should seal just fine.

So I am getting down to fabricating some brackets to mount it and then plumb it and I have some questions. I am running an in tank fuel pump with a return, supply, and vent. There are two filler options: on top or on the side. I will install it on the side and cap the other hole. Tanks provided a plate. Some day I will install a sending unit. Now my questions: What is the barb on the side of the tank for? Is this another vent? Should I just cap it and use the vent on the fuel pump unit? There is also a threaded hole on the bottom front of the tank. What is it for? Should I just plug it?

I will try to send pictures lateron my progress. I may actually be close to putting the body back on.

I have successfully installed the fuel tank but I still need to figure out what to do with all these holes/openings. Specifically I am trying to figure out the hose barb and the threaded hole on the bottom front. The threaded hole is now behind the strap. (and under the masking tape)

A quick update:

The engine is in and the wiring harness is plugged in.
The exhaust is completed.
The brake lines and master cylinder are in.
The battery has been relocated. This required several re-engineerings but now the battery is under the trunk and yet still easily accessible. The battery is hung from the frame and the battery box covers it but does not support the weight of the battery.
The fuel supply and return lines are 95% complete. I am waiting to put the body back on before I make the final cuts on the fuel lines.
The gas tank is in, next I will plumb the fuel pump and cover the extra holes.
The undercarriage wiring harness is installed all the way back to the tail lights. I still need to wire the front end but I need to work on the radiator mounting and get the fenders back so I have something to secure the wiring to.

Once I seal up the gas tank and fuel pump I will be ready to get the body out of the back yard and back on the frame.

Any ideas on how to wire the taillights? I am installing 41 Chevy taillights using the 92 Suburban wiring harness. As you can see in the picture the wiring harness has four wires: black (ground I assume), yellow, green, and brown. The 41 Chevy tailights only have two wires: red and black.

Wiring is not my strong point so expect a lot of questions. Thanks
