How to undo prop with diff already removed?

[rossmc88]

anyone know how to undo the prop to gearbox bolts when the diff has already been removed?

I really should have undone these bolts before I sold the diff

I tried locking the engine using a spanner on the viscous coupling, but it doesn't lock it

Any help would be great!

Large screwdriver thru the U joint to lock it against the car....

22mm socket on the crank nose bolt and bar against the chassis rail will stop the engine turning, but you're still dependant on the clutch not slipping.

This did the trick! Thanks!

Spanner on one end, socket and ratchet on the other.

No need to lock anything.
