Removing the rear wing/wheel arch

[Skyedriver]

It's 26 years since I built the car(sold in 2002 bought back in November) and am in need of removing the rear wing/arch that was damaged by the last owner.
The rear half is held in place with nuts and bolts but the front half is blind and I guess rivnuts.
They all seem to be spinning, whats the best way of removing them and replacing the fixings please?

As an aside, how much room do I need at the side of the car to pull the axle out. Car central in a 9' wide garage, suddenly remembered I had to wheel the car out of the very narrow garage I built it in, to slide in the axle....

Thanks

Tony

If the rivnuts are spinning that is a pain. Use plastic bolts next time. I would angle grind the heads off so you can remove the wing and get better access.

I built my Seven in an small Airchamber and managed to get the DeDion tube in ok, but I think it would only go in from the near side.

Yes, they all seem to be spinning unfortunately. Guessed the angle grinder was the answer........
Once the wing is off can you remove the rivnuts and replace?
Next time? that'll be 2042 and I'll be 89 years old......
