I made some progress on my seat belt bars for my cage. Was wondering what you guys thought of the angled tube from the seat belt tube up to the B piller, I kinda like it but Im not sure if its necessary. Ofcourse I'le put one on both sides.

The bar that its sitting on, That's where your shoulder staps of your harness will be mounted?
If so, you may not want that there.
Picture it, Top of B pillar hoop crumples (nasty and unlikely but for sake of discussion), energy transfers down your new bar and begins deformation of the seat belt bar. Seat belts become tighter. Maybe too tight.
You could also move it out to more above the vertical of your seat belt bar or put another vertical underneath it to move the stress to another location.

Thanks Kert, Yeah I thought about moving it toward the straight vertical leg lower on the radius of the seat belt tube but ofcourse it narrows the pass thru access, not thats its great anyways. Didn't think of deforming and becoming tighter, thats no good. Should I even bother with it??
Dont want to add a bar under it continuing to the floor, impeeds foot area. Not sure what I want to do.
Alot of what that piece would accomplish can be done by adding some bracing to the bend off to the side, Just basically a gusset tube. Obviously not as much though. It's all give and takes. Watch your head clearance.
I don't see any reason for it. Like Kert said, hate to see the thing start crushing you by means of seat belt should the inevitable happen. You've got plenty of tube in that cage already to keep you safe.
What if I ran a tube under the seat belt bar in line with it but down to the vertical leg of the seat belt tube where the step thru cross bar is just above the mount, Would that just be gay?? It would be gusseting the radius of the bend essentially which in turn would keep that seat belt bar from folding down.
what are you trying to accomplish at this point?
I think you have a pretty stout cage as it stands. Are you trying to add support to the B pillar?
Think about getting the lower end of the tube off the seat belt bar. You could go back to the next rearward triangle intersection. How about straight down to the floor above the frame rails? "X" (4 triangles!!)braces are your friend. Just throwing some stuff out there for ideas sake.

I'd rather see a bar from the inside upper bend of the B hoop diagonally down to the rad of the quarter hoops behind the front seats. That would eliminate the possibility of the B hoop collapsing inward on a hard impact.
It does depend on how close to the back of your head a diagonal brace tube would be if in that location though...but I'm assuming there's be a headrest of some sort?

Im trying to brace the B piller, It probably doesn't even need it but it just looks like alot of open space without any vertical type bracing or cross "X" bracing. I want to keep a pass thru from the driver/passenger area to the rear seat area, even if its not real wide. Enough to get thru.
I see alot of cages with a big "X" in the B piller, from upper corner to corner. Thats a strong design Laterally but removes any possible pass thru. Granted it does not support the span of the B piller in the center. Just thought it might be a good idea to support the center of the B piller. Remember its my first cage so Im winging it.
I am going to be puting a Mastercraft Rubicon Bench seat to match my front seats between the wheel wells. A 42" wide seat. I widened my wells to allow for inside tire clearence so my tires dont rub the wheel wells. I have that planned out, should fit nicely with plenty of foot/leg room.
Not that my cage is the best on the planet...but I did a 'V' to brace the "B" hoop while still alowing a pass through to the rear.

I could do that but with the adjustability of my seat, it would hit the bar with the seat adjusted back all the way. Thats way farther back then I need it as far as foot to pedals is concerned so I guess it would work fine. I going to run a Flaming River Colume, the colume in the truck is junk, needs rebuilding. My bud is a dealer for Flaming River so I can get a good deal.
Need to get my pedals in so I can see just how far the seat will be forward of the seat belt bar. I figure it will be about 2 to 4 inckes from it which would allow for a tube like you said. I just wont be able to slide my seat way back.

I have seen it many times, as allways, very nice. Where is your seat belt mount for the harness's. Is there a tube from the V tube to the vertical B piller tube? I cant see it in the pic.
You have the same era floor I do, and it looks like your 'B' hoop is about 3-4" farther back...
I'm 5'11" and with the seat head rest touching my 'V' bar it was a perfect distance from the steering wheel and the pedals in my truck. Unless you're significantly taller than I am I think you'll be fine.

lol! Im a tad shorter, Im 5' 10" & 1/4". I mocked up a tube there and liked how it looked, just was concerned about the seat hitting it. Like you said, it wont. Since my B piller is set back farther by about 3 to 4 inches, and my seat belt tube is leaned back aswell, do you think the belts will be an issue? Right now with my seat all the way back I have 1/2 inch between the tube and seat. In the pic its all the way back, I have to bring the seat forward about 3 inches to be about right with the pedals I think.
I take that back, I think the seat in the pic is close to the right location. I just dont want like 6, 7 or 8 inches of seat belt sticking thru the seat to the seat belt tube, it would look stupid.

I like that, I will give it another mock up with the seat in the aprox. correct location. I think that would be fine.
I like the strength it gives the 'B' hoop...and none of that tube was anywhere near my head.
Cage looks real BTW, very burly and well thought from what i can see.
