I peened mine. It's probably a production assembly aid but I did it anyway.

Same here. A little neater than banging on em with a hammer.
Used a couple sockets, one with a bevel that fit inside the cup, and a long bolt, washers, and a nut. Tighten the nut onto the bolt and it pulls the beveled socket into the cup.
Unfortunately, the beveled socket is an old oil pressure fitting socket that might not be in most tool boxes.

here's my setup. the one socket JUST fits inside the trailing arm...
