Looking for replacement Merillat rear slide bracket

The two pictures show the broken right rear bracket from the side and head-on.  It's not been easy to remove completely, so I didn't do so for the sake of this post. Big box stores have brackets that fit the drawer slide, however, they're too deep.  The bracket I need is 1-7/8" deep.  I believe this is the original bracket when the house was built in the early 1980's.
