It is a bit tricky, just looking at the parts list and some experience on what fits what would be useful.
Following Vander: A 1202230412 is a repair kit for engine mounts. In the parts list it is designated to 043 and 044. It does not show up on parts list for 042. However - when you look for the part by the part number it does show up as fitting 042.
My guess is (as Vander is also suggesting two types) that, as these parts changed at chassis number 042 012864, this repair kit would fit your chassis, because there are parts numbers for mounts below this chassis number (A1802231012), but there are no other part numbers for mounts above this chassis number.
So it looks like for you it is the repair set A1202230412, which primarily fits 043 and 044 cars, but also fits 042 as of chassis 042 012865, this is my guess.
You may also want to change the plate (7), which is A 121 223 04 31 for your chassis no and bolts (8 ) A 127 220 00 71. Upper bolt (9) is N 000931 012120.
The PN you quoted is not recognized by the system.
