Handle support bracket help

hello, I’ve been working my way through the tutorials but my skills are still pretty rudimentary I’m trying to find the best way to attack making this bracket in Onshape. My mind keeps focusing on drawing one side and then feeling like I don’t know how I would continue from there. Thanks for any help

The way those ribs get thicker won't make it easy. Maybe a lofted remove?
Draft
I was going to do a draft but that face that is tangent to the hole seemed vertical.
Given that that face is tangent to the top rounds and it intersects the flange just behind the counterbore, it might make sense to sketch that area from two views and cut it away or add the gussets after. When a drafted surface needs a lot of constraints like this, I'm often tempted to construct those in a sketch, rather than let one end be a resultant of a draft angle. Here you have the side pockets and the gussets which all need to line up in specific places at each end. Seems like a perfect reason for a sketch.
From the second photo it also looks like the top isn't a cylindrical surface - it's two flats which are drafted from a central parting line and then rounds are added.

Here is my workflow for the basic body, (no details, or holes shown, and dimensions are guesswork).

Start with the tapered rib profile (working on the assumption that this part is symmetric in two planes). Then add one quarter body, after that, two separate mirrors. No lofts - no drafts (Hint: use rollback bar in feature tree to see workflow).
Everyone is getting caught up on the tiny details…
How about, what is the function of this part? Are you physically making it? Is it just modeling practice? Are you 3d printing it to replace a broken bracket or something like that?
The real part has features specific to injection molding. If you are 3d printing it, you don't need the draft, or probably the small holes on the back.
