    Does anyone know if there is a manufacturer / supplier of a bracket or mounting kit for a 4L60 trans TV cable to fit a Quadrajet carb ?

    Thankyou Larry. I'll check into that.
    I would also be interested in hearing from anyone who made their own set-up to see pictures and to find out how successful it was.

    Quadrajets were used after the the 200 and 7004R transmissions came as standard equipment on new cars. You could source a carburetor and swap throttle shafts. Maybe not so easy in Australia though.

    Not so easy Larry, probably impossible. The only cars that came with this transmission were the locally produced Holden Commodore models from 1988 - 1995 and they used a fuel injected version of the old Buick V6
    Ken, thankyou for another option. I'll have to look into the spacer thing to see if there's a sufficient gap there on the Nailhead manifold. Do you have a length for that throttle linkage piece please.

    Pointing the arm straight down it's 1.325" from the center of the primary shaft to the furthest edge of the arm.

    The Quadrajet I have is not the OEM for the 1966 Nailhead manifold. However I'm sure it will work OK ?? Model number stampings 17057213 and 3166 AWP .
    Took some measurements and pictures of the throttle linkage and there seems to be plenty of space for the modified arm. Does the new arm bolt on to the original ?

    The TV1 arm would replace a part on the throttle shaft behind the throttle arm. It slips onto the throttle shaft once the throttle arm has been removed. Then the throttle arm is reinstalled - I recommend welding.

    With that quadrajet the lower detent arm will interfere with the TV1. It would have to be removed.

    In reference to the lower detent arm, do you mean the arm below the throttle shaft peened end or the one closer to the camera ?

    Below the peened end

    Thanks for that. I haven't had time to re-investigate this issue but will keep the info for future reference. I have tried to get a later model parts carb to suit 700R4 but no luck yet. If I go down the route of making the bracket I will refer to your diagram.

    you can grab a late 80s monte carlo quadrajet that would have a throttle arm WITH the lower 200-4r geometry in place of the detent arm.

    That throttle arm often has an A stamped on it, and the tv arm is obviously different from the detent arm though similar.

    Monte carbs from that era number like 17087129 and are the Electric E4mE variety. Obviously you would be removing the throttle arm and swapping it onto your non computer carb.

    Thanks Ken , I'll keep looking. It will still be quite some time before I get around to finishing this project and need to take it for a test run.
