The upper and lower engine torque arms are worth checking. Top one is the big bush top right of the engine. Check for cracks with a pry bar or screwdriver. The lower one can be seen from underneath and again easily checked. Renew the top one with the later square bush type along with its alloy housing. You can replace just the bush on the other types but swapping in the whole unit is easier. Lower one is just 4 bolts and can be done in minutes if the front of the car is raised, better on a lift. YT videos are there to cover both of the replacements. Videos for side engine mount at pulley end plus the front and rear sphere mounts too. The rear one of these isn't much fun to replace.
Unless you are a racer and don't care, fitting poly bushes versions of these will transfer a lot of vibration into the car. Sometimes enough to give continuous buzzing to the whole dash.
I found that after I replaced the top engine one if I put one hand on the top of the engine and the other hand on the arm/frame that goes from the bush to the bulkhead I could feel the engine vibration with that hand but none through the one on the arm. I wasn't deliberately doing that to test things, just leaning over the engine and checking things. Wish I'd done that before I changed that bush, it was split, to see if that could be a valid test to check that the bush was doing its job. I suspect that you'd still feel a difference but it wouldn't be as great as with a new bush.
