Default ‘73 Quadrajet on a ‘76 intake-no go!?

I have a 525355 intake on my ‘63 LeMans, which I show as being a ‘76. I had a ‘76 Quadrajet on the car when I bought it, but it has damage to the casting, and after many tear downs and playing with it, determined it’s junk. Cliff couldn’t figure out anything either from a couple states away through emails and pictures. I was using his parts to rebuild it.
So I bought a’73 17054913 off another member here, that Cliff had rebuilt years back, so I know I won’t have another junk parts carb. I just put it on, and it appears the choke linkage is hitting the intake on the passenger side. Aren’t pretty much all Pontiac Quadrajets bolt on’s with Pontiac intakes? I know there are different choke set ups, but never knew it would interfere with actual throttle opening?
