if it fits I think so. don't recognize that mount brand. This is a very easy mount to replace so try it. 1/4 inch higher would level the engine better anyhow. compare it to existing. I don't think they made a 850R AWD. Its hard to believe some one swapped out the rear and exhaust and engine mounts even if they did. Usually people leave the 250 pound boat anchor rear in place and take out the driveshaft. a 13 second car needs 1 hp for every 10 pounds, so 25 extra hp would be needed for the rear to be as fast as FWD R.

tardcart thats just my best guess lol. Mine seems to be a normal v70 base. The pegs and spoiler were put on from an owner in past. Issue has been the vin is showing me this car is an awd. Every dealer i called shows it shipped as an awd. So im under it scrayching my head like wtf i dont see a drive shaft or any supporting hardware and where the driveshaft would go theres a stock looking exhaust. So been fun finding chassis and vin specific mounts

Ok so a final update and thank you post. All my abnormal shaking/shuddering is now gone! She still has plenty of vibrations and a few rattles due to dash/speedo change and age but nothing abnormal. What worked was changing all mounts. A drain and fill trans fluid change. Did 7 total drain and fills with toyota type lV. Fluid was the dark brown( color people say when dont want to admit it was actually black). Also what finally seemed to smooth it that tiny bit extra was a fuel filter spark plugs(old ones were horrendous) and 2 bottles of techron fuel system cleaner. Thank you to all those who gave great advice and stayed with me til the end. This is good bye for a few weeks until something new pops up ;)
