Hi Ive only had my jdm ap1 a few weeks and already have a problem that has made the car undrivable

Basically I noticed it was notchy going into gear on the way to work and when I finished my shift and got back in the car and found I couldnt get it in gear.
After turning the engine off and selecting gear again I was off and all seemed ok just a little notchy

Later that night it happened again, pulling away while turning left the engine was knocking/ clunking hard a similar sound to what a welded diff sounds like.
The car then wouldnt go into gear randomly so I limped it home.
Every pull away from a stop the engine was bucking and hard to get into first gear.

My mate said the engine was twisting to the side with a lot of movement.

I'm thinking its a dead engine/box mount that's throwing my selector out.
I feel its hopefully just a mount as over the last couple of weeks when I let off the gas I hear I swinging kinda clonk

The cars drifted to so a violent transition may have finished the mount

 

My psychic diagnosis is a blown clutch plate.

 

Well I'm about to pull the box off to have a look.

Jacked the rear up and my prop has play in and out.
I started the engine with the car in the air and popped the clutch in and out. Every time I pop it out there is a very loud knocking.
Seem where the prop goes into the box.

Worth mentioning that if I rotate the rear wheel and it will go into gear fine then if I put it back into neutral turn the wheel around spittle more then try and put it in gear it doesn't want to go in

 

Well the prop is banging so guess its worn and regressing may help but that don't explain why my gears are having trouble
