What is the reason why Ford decided to leave the roof members out that we have discussed in post #8?
Because it wasn't needed.
Quick Shift #4 – Ford Gt Crushes the Crusher | EveryThing Driven
There are other options...
]For the record I have built RCR40's with upper door rollcage bars that had quick release pins to ingress and egress but only as track cars, the silver Ford GT (Robertson racing) shown is also a full on GT2 race car and the rollcage is a huge pain in the butt to navigate and not remotely practical for the street.
Thank you for sharing this with us here. Could you be so kind as to post some images of that mechanism?
In post #17, you've said you "have decided not to build a GT40 at this stage, but properly restore another car..."
Given that, it begs the question if this thread should then in the "Miscellaneous Hobby Forums" vs the "All GT40" one.
As for your most recent solicitation of engineering spec and pictures, perhaps the better solution would be to PM Fran, Frank Catt or the other engineers/builders on the forum and offer to PAY them for the design work and intellectual capital you're seeking on your specific restoration project. They then have the choice of giving their designs away or to be fairly compensated for their expertise.
Exactly what Mike and Randy said. This subject has been beat to death. A previous member had your same thoughts for whatever reason. If I remember correctly when his website was up and running in 2007, he wanted like $600,000.00 for his dream machine. Here is a link back to when he was posting. http://www.gt40s.com/forum/gt40-build-logs/16306-progress-giant-one-off-large-gt40.html
