Warp one corner of a body?

So am am trying to make a bike frame in fusion 360, and I have a body for the rear triangle, I want to just push one corner inwards, to have clearance for the chain. I am not sure how to do this, and I want a similar effect that I did for the rest of the triangle, by extruding a thick piece, then cutting out the curve, but I only want it on one corner. Is there a way to do that?

You cannot just "push in" a part of an existing solid body. the only way to do that in Fusion 360 is to modify the inputs (sketches) earlier in the designs timeline.

Do you have any suggestions of how I might achieve this using sketches?

Change the dimension circled in red and observe what happens.

Go through the timeline and browser of the attached design  step by step.

I am trying to just move that one corner inwards, while keeping the top corner connected to the top linkage, and the corner connecting the axle where it is. I just want to move that corner inwards to make room for the chain and chainring, while still having room for the tire. I will attach the fusion360 file. I have also attached a few pictures of what I am gong for. Sorry for my lack of skill in fusion360, I am sure it looks a mess, I only started learning this very recently. Thanks. [Edit: The rear wheel is 29 inches in diameter, and about 2.5 inches wide]

Understood! Did you look at the design I shared?

If so, what did you observe and then conclude based on your observations?
