Carb Return Spring

Need a little help please.
I need to know where on a '66 396 the carb return spring attached too, besides the throttle lever. With replacing the thermostat housing w/ an original, I now have a tab on that. Plus I have the small standoff on the upper alternator bracket. On this, there's 2 holes, an upper and a lower. I found Wilcox Corvette has the throttle return springs. But here's the catch, This motor has an Eldebrock 2.0 intake and a 1407 carb. Will a stock spring work?

It might but you would have to try it to find out. Modern carbs are controlled by throttle cables and have the return spring on a bracket at the back attached to the bottom of the carb. As the throttle rotates open the spring attached to the bottom of the shaft opens up (stretches). Your original; spring attached to the top and went to the water neck that had a tab cast into it with a hole.
