How To Replace ALL 5 Engine Mounts Euro 3 D5/T5 - DIY Volvo V70 S60 XC90 S80 P2 Vacuum Front Rear

I had quite a lot of shaking inside the car like a ferry idling in the dock. After finally getting the Timing Belt and Water Pump done it was time to get on with all 5 engine mounts. The parts I used were: Front Vacuum Mount: Volvo 30680751 Rear Vacuum Mount: Febi 22673 (Volvo 30741397) Right Side Engine Mount: Febi 22687 (Volvo 30748811) Upper Engine Mount/ Sway Bar: Firstline FEM4123 (Volvo 30645447, 30776354) Torque Rod/ Gearbox Mount: Febi 22711 (Volvo 30680750) The reason the parts are mismatched is I was originally quoted for all FEBI parts totalling around £220 however since Brexit (?) all prices appear to have increased and the front vacuum mount was double the price of the rear vacuum mount. I couldn't see a difference between the two so I asked my local motor factors and Volvo Parts (Mill North East Volvo) on eBay however neither could answer correctly. The rear mount has an extra piece of rubber on the bottom where the front doesn't.
