My 93 Park Ave has broken. All 4 of the front subframe mounts on the back side have broken. Just wanted to know if anyone knew of an afermarket part due to GM parts costing about $400 . Seems expensive for rubber cushions and steel bushings. Thanks for any help.

i am also in need of subframe mount kits for a '98 bonny se. any aftermarkets available?

To the best of my knowledge no. You would need to go to a dealer for the mounts.
