the sleeved were busted because the upper control arm ball joints screw into the upper control arm. they are not press out ball joints.
option 1 - find replacement sleeves (don't know if they're even available)
option 2 - find new upper control arms for an e-body (hard to find and expensive)
option 3 - be a demanding customer and required the shop to replace what they ruined. because these upper balljoints are screw in, they should have been screwed out. because the shop didn't know, or failed to check, you could try to hold them responsible
sorry, this happened...sucks big-time
