Demon carbs mounted sidesaddle-need to cut bracket?

I'm fitting up my dual Demon carbs to my blower and have run into a small problem regarding throttle bracket clearances. On top of the blower is mounted the carb adapter for 2 4-bbls. The front carb fits just fine on the adapter plate, but the rear carb doesn't fit because the bottom part of the throttle bracket hits the top of the adapter plate. The front one fits since it hangs out over the front of the plate.
I'd like to just cut off the bottom of the bracket on the rear carb for clearance, but before I do, I'd like to get a few opinions.
I don't want to go with any spacers between the carbs as the whole assembly is very tall already.
The only thing that I can see is that I won't be able to use the hole for the throttle return spring. My return springs were going to be mounted elsewhere anyway.
I've attached a pic showing what I'm talking about. Anyone see any reason why I shouldn't do this?
Thanks!

Steve

There's no reason you can't trim it. I've got the same setup on mine but did use carb spacers, heck, what's another inch, he he!

Same problem with Holley 750s

Had the same problem with the same piece on my rear Holley 750 and the blower adapter. Just cut what is needed, no problem. Mount the return springs using a mounting kit through the big holes on the same piece.

Steve,

Some of the Blower Top plates are recessed there which is why we leave that portion of the linkage in place. There won't be any harm in triming that, you'll just run your return spring to the top of the linkage arm going to the passenger side of the engine.
