The battery box hit the frame before it reached the rearward edge of the opening in the floor. A piece of 18 ga. about 2-1/4" wide was fitted and welded to the opening. While I was grinding the welds I also cleaned up a few more of the many rosettes attaching the tail pan to the floor.
Before filling the front of the hole in, I wanted to locate the grounding lug. A cable will run from the lug on the box to the lug on the frame. Locating the lug now will allow me to make the cable now. After locating and drilling a 5/16" hole, the frame was tapped with a 3/8-16 tap. For now, the stainless nut was welded to the frame in two spots. When the body comes off again, the nut will be completely welded.
Finally, a piece was cut for the front of the hole. I got the beads rolled, but ran out of time. It is supposed to be about the same temperature on Saturday as it was on Friday, so I should be able to get it in tomorrow.
Another short day. Waited until it warmed up a bit and then put up Christmas lights. Probably only worked on the car for about 3 hours.
I finally decided on 1/0 for the battery cables. A hole was drilled in the front end plate for the waterproof strain relief.
A 3/8" heavy stainless steel nut was welded to the side of the box. A length of 3/8" brass all thread will be installed here and nutted on the inside. The negative battery cable will go to the stud, grounding the body. The outer stud will have a cable connecting it to the frame.
I still have to figure out how to attach the lid and then build it. As for now, the floor will need the extra panels put in and then the box can be installed.
I decided the best way to bring the battery cables through the floor was to extend the raised portion rearward. A section was removed and a new piece was formed and welded in. The welds still need ground smooth.
The bottom of the battery tray and the box underneath of it received a coat of POR 15. The tray was then welded to the bottom of the box.
I have to decide on how and where the battery cables will pass out of the box.
Another short day. Cold in the morning, getting dark real early, and the honey-do list all take their toll.
The relay mounting bracket was welded to the fuse box mounting bracket so they would be easier to install.
The cover for the turn signal and cruise wires coming out of the column needed some form of support. I thought about building a strap out of sheet metal. I decided to cut the "wings" off the original column support and use it.
After cutting it, I made a bracket to mount the turn signal connector. The bracket was welded to the modified column support and then the mounting clip I cut off the column previously was welded to the top of the bracket. This positions the connection near the fuse box and out of the way of my foot when braking.
