6476 Roll Cage

accobraaccobraMember
Ok so I found some time to reposition the rotissere and complete the roll cage probably as far as I want to take it ... maybe I will add cross braces at the doors openings if I can find seats that I like in time ... Seats ? I would like to duplicate the RARE GR 4 seats with the white and black ladder effect .. they kinda look like COBRA seats ... anyway heres my progress.

Awesome Ron! Neat to compare 2 different setups. I see you welded yours in. No getting it out eh? I just finished my headers so I am about to remove the engine and finish up the removable section which runs through the rear window. Mine comes straight back before coming down so I can tie into the roof line at the decklid hinge before coming down.

Wow ...now thats a scary thought.

Well I have a lot of little details on the body to complete .. along with the front valence to replace. And some reinforcing to do with flat plate steel

I want to try to lower the floors ?

I have to fit the fuel cell in the front ?

I want to add either a GT 40 scoop or 3 tear drop scoops like the SHelby or Ferrari GTO had to the hood.

Then blast the entire car ... gonna do it in my drive way. Then prime and skim coat the entire car.

Another year ... sooner if the guy who I want to hire shows up ... he does body work on the side... with some real help .. by summer.

Johhny Thanks ...... after a race 9138 @ Pocono some small cracks appeared .... it was pretty easy to see the exact stress areas .. mostly the roof posts.

Joules all of this was based on the SCCA Rule book for thickess of the Tubes and plates ...some minor issues exist having to do with the size of the plates on the HALL bolt in cage that are too small ... only think not there is the cross bar in the door area. Still contemplating that and how I want it installed.

NICE WORK RON !, can you still get the bulkhead cover in and out easily with the bars welded in ? i seem to recall in my last pantera , i had a hall 3 point bar bolted in and it made removal a real PAIN!..........i kept that bar when i sold the car and was going to install in my current pantera, but when i test fit the bar, it was a VERY tight fit with the door panels installed !,you had to really slam the doors to close because the arm rests HIT the bar, and the center bar was a bit intrusive for the passenger....i still may use it, not sure yet.... good luck with your project,..........DAVE

That 1/4 " steel flange has 2 purposes. One it ties the rear roll bar into the roof support ..that was your idea ...and a damn good one I might add... the other it acts as a flange to accept a gasket or seal around where I will have to cut the lexan.

Yes the brace I bought at McmasterCarr ... I reallize it may not work ... it will involve a whole lot of aluminum welding that I;m not sure I want to get into ... but after adding all that cage ..I;m starting to lean toward wieght reduction ...way back when my 66 Comet Drag car ended up on this track ..and in its final glory it wieghed 2950lbs with me in it ... that was lighter then the Mustangs.

I've seen some Panteraa that had a tube run through the rocker panel tubs, bolted to the front inner fenders and bolted through to the main hoop at the main bulkhead.

It doesn't even need to be a round shape. I've seen it as a 2x4 shape.

If you think about it. Once it is tied to the rest of the cage, it has become a chassis.

Something to think about but where does it all stop?

I can't say it was my idea. I have seen photos dating back years with guys doing it. I have also seen old photos of guys without roll cauges using the cross braces where the deck lid goes so that ain't new but it isn't practical. I think when you tie it all together the way we did it has to do good things. I thought about even a removable cross brace across the back bars but we'll see. I am not sure if it would interfere with the webers and as you said everything we do just adds weight.

I did get rid of the A/C which was close to 100lbs. I don't use a/c even in my daily drivers. I like it hot so I am good with that.

Do you have any pictures of this? Thanks.
