    Don't have my car real handy to look, are the 16 nuts that hold the airbox and air horns to the carbs serviced with an 8MM wrench?

    Thanks,
    Doug

    8mm is correct

    I use a 1/4 drive socket on a wobble extension rather than a wrench. 5/16 or 8mm.

    Yes, a wrench would be quite ponderous on the nuts and quite difficult on the 4 forward nuts.

    I use a ratchet type box wrench and it works great.

    I am going to order a couple nut drivers and modify one so it can be used with the deck lid/hood on the car, which is why I asked.

    I never did get anything that fit really well, as the reliefs in the airhorns were too small to let a 1/4" extension really fit for a true vertical drive, so everything was always done at an angle, though it looks like an integrated U-joint/socket in 8MM would fit in from an angle nicely, ordering one of those also.


    The outer forwards were always a challenge with the hood on the car, it can be done, but is a PITA, and yes, I have always used an open end wrench on those, with the hood on.

    Thanks,

    Doug

    I can get the whole rear bank and the 4 rear nuts of the front bank with my Craftsman nut driver with a 1/4" 8mm socket. For the front of the front bank I use a 1/4" ratchet with the extension and the socket. It just clears the air horns. Removal takes only a few minutes. This can all be done with the hood on my '77 GTB.
