Topic: Exo cage thought

[dweinberg01]

I am going to put an exo-cage on a 95 4runner.  I also want to put in 5 point harnesses in the front seat. What do you guys think about caging the exterior but not having an exterior tube at the b-pillar (this will allow the back doors to open cleanly).  Instead, I was going to cut holes in the roof and run the b-pillar down tubes inside with a cross bar inside to attach the 5 point, and also have a bar outside the cab tying the exo cage together side to side.  I would use floor plates to tie the b-pillar bars to the frame (sandwich the body between the plates and weld the outer plate to the frame using tubing) and the top of the b-pillar tubes would be welded to the exo cross bar. I would also run  an X sung the inner b-pillars and the cross tube for strength.

If you understand what I just typed (cuz I'm having a hard time understanding what I just typed), any input is appreciated. Would this work?

i would look up partial exo's   there are some out there doing almost exactly what you are talking about.  Im not an exo fan, but being as big as i am im thinking a forward cab exo might be in order

i think that would work, just make sure that you properly triangulate at the b-pillar. also make sure you seal it with silicon or something that has some give to it since the cage will flex independently of the body a little, especially if you roll or pivot on the exo.

I plan on doing something similar but instead of cutting holes in the roof I was going to sandwich the B pillar bar to the roof bar and run A pillars into the fenders

If this isn't going to be used as a dedicated trail rig, you might want to consider making the B pillar bars removable using tube couplers.

This would allow you to have the support needed on the trail while allowing the doors still open when not wheeling, and build the 5 point harness mount as its own system w/o having to cut/weather seal hols in the roof.

Interested in this.  Some day I  will go exo. I barely fit in my Taco as it is, so no interior cage.  I really do like Matts cage...."undoing a brocoma" or whatever it's titled.  That guy can build!  I think it is here and on the PBB. 

It is not four doors but there has to be some inspiration and education in his thread.

I like snowtoys suggestion.  With a removable bar, tube location won't have to be compromised.
