School me on Eddy's

Edelbrock recommends an adapter that is a thin (very) metal plate with 2 gaskets for each side.

On the carb, you will need the throttle adapter. It moves the linkage away from the Holley carb (it’s in tighter than the stock stuff) towards the drivers side and repositions where the throttle cable hooked up by a smidge.

I have never seen a “Fuelrail” for carbs. A metal fuel line is probably what there recommending to use. It connects at the rear of the carb and runs the fuel line down and under the carb nicely and ends at the passenger front of the intake manifold. I like this part myself. I’m short a the use of rubber hose. After a while, I dries out and cracks. Which can leed to fuel leaking.

Use the one with a “Barbed” end to use with regular fuel line and a worm clamp.

Your intake has a TQ spreadbore pattern.
The QJ has smaller secondaries.
