Isn't it all in the "Rat Trap"?

It seems just a rod and a clip go to the carb, and all the linkage is on the "Rat Trap" assy that bolts near the back of the intake with 2 bolts? That is the same AFAIK for all the early 352-390, and there is another type of rat trap assy for the 289 cars but the same setup. I'd think a rat trap from any car with the right engine block would work wouldn't it? Easy swap meet item -
