Cage install in Progress
Cage install in Progress Well,
The cage install is progressing!
On friday night, I finally pulled the dash out of the car and started tearing into the heater box and air bag.
On Saturday, I got the floor plates welded in place. And started fitting the front down bars.
Then yesterday I got the main hoop, the rear down bars, the front down bars the front halo bar in and the Drivers door bar all in place. I'll try and get some pictures up this evening.
I have a question for some of you technical types. It has to do with how this sentence is worded.
If you take out the () and Commas, it reads, Unless an OEM frame rail is located below and outside of the drivers legs a rocker or sill bar is mandatory in any car with a modified floor or rocker box within the roll cage uprights.
In my case my floor is unmodified and my rocker box is outside of my uprights... So am I legal without the sill bar?

Unless an O.E.M. frame rail is located below and outside of driver's legs (i.e. '55 Chevy, '65 Corvette, etc.) a rocker or sill bar, minimum 1 5/8-inch (41.2 mm) x .083 (2.1 mm) CM or .118 (3.0 mm) MS or 2-inch x 2-inch x .058-inch (50.8 x 50.8 x 1.5 mm) CM or MS rectangular, is mandatory in any car with a modified floor or rocker box within the roll cage uprights (excluding six square feet of transmission maintenance opening).
In my case my floor is unmodified and my rocker box is outside of my uprights... So am I legal without the sill bar?

They way I read it I agree with you Ryan, not needed. Although I think Ellis has them & might know the answer. I'm adding sill bars because my wreck showed that is the weak spot in the car.....

Well, the passenger's side air bag is sitting on the shelf in the shop, most likely its final resting place. That is, untill I get a chance to blow it up. How many NHRA drag cars have air bags? Also, that is one heavy SOB.

I was just at a plant in eastern Washington where they make the explosives for the airbags - talk about a scary place. Most of the walls in the manufacturing area were 42" thick on three sides and just sheetmetal on the fourth side - just in case. Some building had a 40' berm surounding the building and many were refered to as 'magazines".
They sure are heavy and I know why.

Actually from the way that reads I think you are required to have sill bars because of the example they give is actually of a full frame car with a thick gauge exterior frame running along the rocker. Your car is a unibody and basically the only "frame" you would have right there OEM is a sheet metal stiffened rocker.
And btw my understanding is you are really not supposed to have an airbag when using a harness. Something to the effect of the airbag being designed for you to kind of lean into it at impact basically meeting it before its at full capacity softening the blow. The factory seat belt allows you to do this but if you can no longer lean towards it because the harness holds so firmly the airbag hits you at full velocity.

I will let Ryan chime in but when he first got the car I asked the same question about the seats and I thought he said the previous owner had had them covered like that. I could be mistaken though.
They looked very nice. That is why I remeber.

Sill bars are coming. I chose to put them in now and not have to rip the car back ap rt later. I 'Think' the Driver side is required now. When it was Certified it was good to go.
After seeing how weak the rockers are I would not even question it. they buckle if you breath on them hard
The car sure feels good with all those bars in it
If you look at the way the front bars fit you will see why I did not like the way that set fit Heck that l that looks like my old Morrison kit
