FB Cage Chassis Dimensions CAD Measurements

Sorry about the title... just for search purposes.

I'm building a cage for an FB and recently purchased a copy of bend-tech. As much as I love laying strings out and getting coordinates, I thought it'd be wise to see if anybody has already done this for the stock FB chassis.

If so, I'm looking for XYZ or LRA coordinates for cage bend locations. If you've got em and are willing to share, it would be most appreciated. Bend-tech files are appreciated, but I can work with just about any standard CAD file. Thanks a bunch.

If you get them, or end up taking them yourself, I would love a copy of them in an autocad format, if you dont mind sharing. I would help out, but I do not own an FB, but might be working on one in the future.

For a 'one off' cage I wouldn't waste my time with CAD stuff. Measure the car's interior width and height for the main hoop, in the general location you want it. (go a little tall in case you want to lay it back a few degrees) Use bend tech to tell you where to bend it to make it fit those dimensions. The most important thing is to know your bender, the bend doesn't start at the edge of the die. Keep in mind you need to be able to weld it in later so don't make it fit so tight you can't get around all the tubes.

The rest is just a matter of making tubes fit where you want them and to the main hoop. A halo is easier to make for the top because then you only need one bend in your A-pillar bars.

On FB's I cut the stock roof reinforcement area above the door window. I slot it front to back so I can pound it in and out of the way. It will give you about an inch more room for your head/helmet/padding. The other trick is to tilt the drivers seat in at the top just a little, you won't notice it when driving.

Do you guys mine posting up some cage pics, we started a s&w cage and it is all over the driver's head area, enough to not feel safe.

As it was mentioned, just get out there and do it. CAD is nice to figure stuff out, but for a cage it is much easier to make measurements on the actual car!
