Alright, finally got the crank bolt off. I flipped the engine upside down on the ground and wrapped a trolley jack handle with some rags and shoved it through the crankshaft and into the cylinder to stop it moving. Then for the crank bolt I used an exhaust pipe on my ratchet to give me some lever and with my feet on the engine while pushing the trolley jack handle the opposite way, gave it some elbow grease and it loosened

Used a 10mm spanner to remove the clutch bolts the same way while the handle was still through the crankshaft. I wrapped it good to avoid scratching or damaging the cylinder.
Btw, I had to use a impact socket as my Stanley socket with Lifetime warranty split the first time I tried it.
Now to remove the flywheel bolts...gonna be another ball breaker day
