It's basically a length of flat steel bar, a metal fabrication shop could easily make that piece for you, and even make it out of heavier gauge material if you like. Posted via the PriusChat mobile app.
When I click on the part number link given in post #15 above, the first ten search results I get are all Toyota dealer, amazon, or amayama links. It doesn't seem difficult to find.
Hi Yes it’s just a straight metal bar with 4 holes on each side but why can’t I find the part number in Toyota directory. This bar came with 2014 Prius lvl two and looks like Toyota doesn’t sell replacement rod.
link from post 15 part number 53605-12021 doesn’t fit with 2014 Prius. As of right now there is no aftermarket reinforcement bar for 2014 Prius. I do see for gen 1 ,2 and 2010-2013. I have been looking 2014 and 2015 reinforcements bar oem part number and there isn’t anything here. I also called Toyota parts and they have no idea without the part number.
I see 53605-12020 here: Floor side member for Toyota Prius XW30, 3 generation, restyling 12.2011 - 11.2015 - Toyota Car and Auto Spare Parts - Genuine Online Car Parts Catalogue - Amayama
Amayama can have superseded parts, at least that was the case with my oil filter conversion, where there was several versions. There must be a reason for revision, but older part is hopefully serviceable.
