I busted off same side on my 2014 Trail wheeling. Did not find parts other than entire replacement.
Ordered from here:

I have found what I needed for mine from here and at prices lower than my local dealer or repair shop.

I actually had the bolts to the front skid plate work loose and drag the skid plate. I blame Toyota service but can't prove it. Check the four bolts to be sure.

I have a 2014 Trail w/KDSS and put the SSS bumper with SB winch and it sagged bad, my bottom clearance was 7". upgraded to OME 3" with medium weight springs, got my height back up and some, clearance at 11”. Very happy!
