340 kickdown linkage 1971-2

The current linkage is for 1973 Holley 2210 2 barrel. I was thinking I need the whole assembly. Don't have to use Thermoquad, if there are better spread bore options with an electric choke. Was looking at Holley Demon 1900/1901 and wondering if I can mount it with just a gasket and if their linkage adapter will work with Chrysler linkage. What do you have?
