what type and size plate did you use to attach that bar to? was It to just one plate in the floor of the cab that was welded to the floor, and you precut a big enough in floor to weld the tube to the bottom of the single plate? Did you do anything to the stock cab mounts you can see in that picture. And if you have any better shots of the bars connecting to the v bar could you post them please. Did you use smaller tubing for the seat mounts?
thanks a lot going to be getting started on mine this week hopefully, when I get my truck back from the shop.....
The back hoop in the cab that the tube is from is 3 pieces. The piece you see in the picture is about 12" long and goes from the frame, through the cab, and sticks up about 6" from the cab floor. It is then welded and plated to the main structure of the hoop. Same thing on the other side. I attached another picture of the hoop in back.
I wouldn't trust the frame to be strong enough to butt weld a tube to it on spots that take a lot of the load, I'm far from an expert but my friend and I built a little shock hoop to hold a 2.0 in high school and the hoop actually teared the frame. Sure it was poorly designed and it was a heavy suburban, but I was amazed how weak the frame was. I think a lot of people plate the area of the frame and then weld the tube to that
That cab cage isn't even really built yet in that toyota. The back hoop was just put in so that the rear of the truck could be built. Once the in-cab portion is built, everything will be reinforced and gusseted. The whole point of a cage is to distribute loads so all the pressure isnt being put on just one mount.
