School me on Eddy's

Sorry if this is in the wrong thread.
I don't have much experience with old cars but I have always done my own maintenance on my vehicles. I have only ever dealt with Holley 4bbls but I recently got a screaming deal on a brand new Edelbrock 1906 (650 cfm AVS2) and I am really excited to drop it in my Mopar.
I have a 100% internally stock early 70s 360 with headers and and Edelbrock performer rpm intake hooked up to a 727 auto. What parts will I need to convert from my holley carb to this edelbrock? My intake has a quadrajet style opening instead of a square bore that seemed to seal fine under my holley but the edelbrock site specifically recommends I get the adapter plate #2732 to seal the carb to the intake. Is this necessary?
Ive also seen recommendations for a new fuel rail (PN 8126? / 8131?) but I am not sure which one I would need?
Last one, Which kickdown linkage adapter would I need? Ive seen a few different part #s online and prices seem to vary a bit but based on the pictures they all look the same?
Am I overlooking something or am I overthinking it?

My car is basically just a cruiser so at the end of the day I just want it to be dead reliable and hopefully for everything to work right the first time without major leaks or fires

I think what you'll need is the spread bore to square bore adapter if your Holley is spread bore, most Eddys are square bore I believe. I also switch back and forth between a 600 Hooley and a 750 eddy and it bolts right up to my performer manifold. ypull need the edelbrock chysler linkage bracket, and swap over the cable and linkage hookup posts from the Holly to the eddy.

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.

Thank you for the responses.
My Holley is a square bore, and the intake is a spreadbore and yes I was referring to that metal fuel line, not a "fuel rail" (Thanks @rumblefish360 for the correct terms). Ill buy the adapter plate for the the edelbrock then
