Roll Cage Floor Plate Questions

[goathearder]

Hey Guys,
I am nearly ready to start building a cage for my K5 and I have a couple questions about floor plates:

1) From the B pillar back, the floor of the truck is not flat, its channeled. Do I have to do anything special with the floor plates or can use just sandwich the channeled floor and be fine? I was thinking I would have to build the plates with support for the channeled areas but I wanted to ask first.

2) I have a "factory" style roll bar in right now and the floor plates for the B-Pillar rest on both the floor and the wheel well. Does doing that provide more strength than just the floor itself, i.e. should I mimic that with my new floor plates?

Thanks,
John

I did not have a factory bar in my '84 K5. I know what your talking about near the seat belt attachment on B pillar at the floor area. I ended up using 1/4" plate and building it up. and then used 1/4" plate under the truck to sandwich the body between the plates and used grade 8 bolts. I think building it up inside will spread the strength out instead of having an open area under the plate where the floor is lower. know what I mean? It took some extra work to cut the step (filler) plates but I felt it was worth it. It only required 2-3 extra plates from what I remember. I can get a pic when I get home if you want.

Yea, a pic would be great but I think you are talking about exactly what I am thinking. I feel like building the filler plates is probably the best way to do it and why skimp on something so important.

Here is what I did.

Same thing as Mix. When I tie it into the frame the bottom mount will get welded solid with the frame mount.
