Rollcage in fiberglass tub

Okay, theres one good thread started on this, but I have a different need.
I have a 77 CJ5 with a fiberglass body. I was planning on building a roll cage that sat in the fiberglass tub, with the seats tied into the cage. I was gonna use channel iron as the base to build the cage from. After looking at recent threads, I'm not sure this is doable. I'm hoping to buy the front hoop, and tie it all in myself.
The reason for this is I'm worried about the 55 MPH road on the way to the trail.
Will seats stay tied in on a fiberglass tub in a hard collision? My only worry is that my little girls walk away from it. I can buy a new body anytime. This Jeep is a third vehicle, so it doesn't have to be every day convenient

you can simply drill holes thru the tub and weld brackets to your frame thats what i did. i as well have a cj5, but only the normal roll bars, but i drilled holes, extended the bars down with steel tube, and welded onto the frame.. same with seats, drilled holes underneath made brackets and welded to frame. didnt want my fiberglass to rip if i flip and throw my seat.

Another way is to use a store bought roll bar and front loop assemble (4WD) . There is also a cage extention that lets you bolt the cage to the frame. This way the holes you drill throw your glass tub are for the bolts.
So in effect, you can unbolt your cage if you have to take the Jeep apart.

Fuzz,
Did you bend the tube yourself or did you use a kit?

bolt on cage?? doesnt sound safe, especially when you flip, and the pressure snaps a bolt in half... i can snap a bolt in half just buy putting too much torque on it with a socket wrench, i think gravity is stronger than me too =] ... just my 2 cents

There is nothing wrong with bolting the cage in like fuzz401 did his,,It is hundreds of times better than just bolting it to the body in my opinion like jeep does from the factory anyway..I will be doing mine along the same lines as he did his very soon..My factory roll bar is just bolted to the fiberglass body now by the previous owner (For looks I guess)..I need to find a shop in my area so I can get mine done as well as a friend of mine's CJ...
By the way very nice job fuzz

I guess I missed my point!
With the plates at the botom of the rollbar foot. I would run the bolts throw the body to another plate attached to the frame extension. The 6" square plates will be bolted together. The roll bar extension will be welded to the frame. This way you can remove the body and or cage without cutting up the roll cage. If you can't fab it yourself. You can purchase everything from 4WD or Quadratrac. I'm sure there's other companies too. My fault for not explaining myself better.
