Thanks guys

I will be working from underneath as i have got access to a 2 pillar lift.

Could i just support the engine from underneath then remove the 4 crossmember bolts & the 2 nuts on the top of the old mounts, then lift the engine up with a gearbox jack, remove the old mounts then put the new ones in & lower the engine onto them?

Will this work? Sounds like it's gonna be alot harder than it looks
