That is why it is recommended to simply dismantle it.

Last but not least from the gearbox side. Raise one of the rear wheels and place the body on a rigid support such as a tree stump or double brick stack. Using a screwdriver, bend the locking tabs located on the front propeller shaft seal. Use the same screwdriver to push this oil seal back. Then, using a wrench or socket wrench, unscrew the cross member fastening nuts and remove it. Surely, parts of the exhaust system will interfere with you.
