Hello all, I have a problem I'm not sure how to tackle here and could use some advice.

For reference, my car is a 1998 S70 base model, no turbo and manual trans.

I was doing the mounts on this car since they were pretty thrashed. I saw the top of the transmission had holes that didn't align at all, so I looked up the part number on the top of it (Volvo P/N 1397889) and saw it was the rear engine mount that seems to bolt to the transmission.

So I jacked up the transmission and aligned the holes so I could stick something in the bolt holes. Unfortunately, the top and bottom bolts appeared to be sheared off flush in the threads or even indented a bit. What would be the easiest way to solve this problem? Without this mount the engine will sit way too low on the driver side. Is there anything I can do to solve this without pulling the engine or transmission?

Also, as a side note, the bolt that should go here appears to be Volvo P/N 982820. I'm not sure how long these bolts have been sheared, but the car has been sitting a long while, and I'm trying to get it back into shape. So it was likely damaged with the previous owner.

I also just did the passenger side engine mount too since that was shot.

If anyone has advice on how to solve this problem, I would greatly appreciate it :)

I can’t see getting in there and extracting a bolt without pulling the engine, sorry. It’s pretty tight in there. Maybe on an NA engine you can pull that off, on a turbo not a chance.

I see, well on the NA at least there seems to be a bit of room, I was able to remove the mount and I might have enough room to extract the bolt it seems like. What would be the best method to do so here?
