Buick PA – Subframe (engine Cradle) rusted through

Hello US-CAR municipality, today a very sad news. When the workshop wanted to change the engine carrier bearings she found out that the photos are flawed. There does not seem to be a proper support surface for the rubber bearings anymore. The whole is called Frame Kit or also Subframe or Engine Cradle (88952019) but nowhere else can I find it new. Is there someone who still has such a motor carrier for the PA and which is healthy? My second consideration would have been the dare Is this possible at all? Until I have found such a frame, the PA has now been pulled out of the traffic. I am grateful for any help, don’t have to be on the crossbars that are only a few months old with my PA. Dejected greetings, Tommy
