    So, I'm looking the motor over in my 69 GS400 (original 400 motor), getting ready to pull the intake manifold. and trying to get together everything I need before tearing into it. I picked up a 2146 Performer intake manifold for it and have a question about the divorced choke on my Quadrajet #7029240.

    Is there a separate thermostat and rod that I need to get, to bolt to the intake, to make the divorced choke work?
    If so, where do I find them?

    It looks like there is a place to bolt something on to the manifold, but my stock set up looks different.

    I search around and could not find a definitive answer...

    Thank you!

    Thank you Larry! That is exactly the information that I was looking for.

    I'll probably try the TA Performance kit first.

    The "Chevy choke thermostat" (and cover) you have pictured looks exactly like the one I just got done dicking with two days ago, on a '77 Chevy half-ton pickup, 4WD, 350 engine, Q-Jet.

    The TA price for choke 'stat, screw, and cover, is less than the NAPA price for the bare choke 'stat.

    Coat-hanger links "can" work, but sometimes the mild-steel of the coat hanger is too soft to hold it's shape. A welding rod of the right diameter--or larger diameter, with smaller-diameter ends welded-on--may work better.

    Coat hangers will work for a rod, but there very hard to bend in the needed short tight angles without heating them with a propane torch to a red state.

    Once your done bending it into shape heat the whole rod up to very Red looking in a brite room and toss in in water and then it will be ridged again and hold its shape, but before that step cut some notches 180 degrees apart so you can get small Jesus clip on it to hold it at each end.

    If fact you might might want to cut these notches first once you see how long of a section of rod you will need, since a straight length of rod that you can hold in a vise will be much easier to cut notches in with a Hack saw.

    Sounds like a good item for someone to reproduce and sell...

    Thank you Brett! I'm assuming the "2.80 OVR" means an over-all length of 2.8", before it is bent? Looks pretty simple to do.

    That would be a great idea for someone (like TA ?)
