I had the same problem ... former owner had overtightened the screws in the lid that anchor the latches. Went to AutoZone and found one putty there that was labeled for use with ABS plastic ... no other kind works (except things labeled for ABS). This is a two part putty similar to the metal putty everybody uses. You work equal parts together ... it gets very warm ... mold it to the desired shape and press tightly into where you need it. Then I let it cure (just minutes) and ground away excess with a Dremel tool ... seems as strong as original or better ... holding nicely.
