When I originally built my cage, I was in a hurry since EC4RJ was a day or two away, so I made some compromises with the rear section of the cage and tied it into the stock bar. I never liked it so it is time to change it up. Picked up some 1.75" DOM and I am now ready to start. Last night I started with this.
Two hours later I ended the night with this.
Doesn't look like I did much, but I also have my cage foot plates installed and am ready to start the mockup.
Plan is to have a verticle C-Pillar behind the rear seats with a D-Pillar angles down at the back of the body. To tie the two sides together, I may just go with a simple straight tube or go with a halo type tube with two kickers. Bending will start this Sunday.
Got the tubing bent up in the morning for the 4 Runner. Finished up the frame mounting plates and started to set the tubes in place. Got the main structure tacked in as well. One issue I am running into is that my original cage is made from .120" wall tubing, but the tube I am using for the new section is .125" wall so I can't use the same inner tube sleeve that I normally use, which would be 1.5" DOM.
I have some 1.5" x .25" DOM left over from my steering linkage that I am going to have half turned down to fit in the 1.75" x .125" DOM that I am using. Once I get them turned down, I can fully weld everything out. I have about 7-8 more tubes to install, but this is how I left it at the end of the day yesterday.
Short Fab Day 3
I got some 1.5" x 0.25" tubing turned down to fit as a slug between the two sections of tubing and installed them with plug welds. Added a few more tubes, two of which took a decent amount of time to get just right. Also notched and re-bent the original tube in the middle to intersect with the new horizontal bar of the C-pillar. Three to five more tubes and it is done. Here are the pictures.
