Hello

I'd start by checking for worn mountings - check the tightness of the engine and gearbox mounts and their condition - this is best done by using a jack to take the weight of the engine off the mounts and seeing if any cracks or splits open up in the rubber.Also check the tightness of the mounts bolts

also check the propshaft : then I'd suspect that the propshaft either has a worn joint or the centre bearing is worn

you can easily check for for any slack in the propshaft joints by twisting either half by hand and feeling for any play as there should be virtually none

the centre bearing is quite loosely mounted so this can be moved normally but if you can run the car in gear with the wheels off the ground and then feel the centre bearing housing for vibration if there's any then consider replacing the unit
