72 340 choke style

So my 73 Scamp has a 72 340, with an edelbrock 2176 intake. I have a stock thermoquad I’m going to install but I need a stock choke. All the reference I find shows the style with the bathtub and gasket, but both my aftermarket Edelbrock and my 72 factory cast iron 340 intake have the open well. I need the correct factory choke that works with this well and a stock TQ.
