2021 THOR ACE 33.1 and Rear Sumo Springs Clearance

Sorry to be asking too many questions. But I feel better asking the question here hoping someone already have the experience with this item.

I emailed Sumo Springs directly to ask fitment on Item #SSR-187-54-1 (Rear Springs). I was told "We can confirm that the part number you provided are confirmed for your Thor. Please note on the rear, some coaches will have a metal weld bracket from factory that can block the rear installation of the kit. Please check and make sure no blockage on the frame. If so, the rear kit will not fit".

I am not sure what that metal weld bracket they are referring to. Anyone have idea what they are talking about (before I order the part for the REAR)?

It's those oddly placed angle iron or square tubing pieces which seem to be welded to the frame and extend up to your floor.

You'll see them and think it's kinda scary.
If one is where the sumo goes, you'll have to move it, or move on.
Below is a link to most of my modifications either accomplished or pending.
