Bugger- broken drivetrain :(
 

Not quite sure whats broken at the moment though... suggestions welcome..

• Big bang at circa 140 (on track at Aintree)
• Still have drive although its making a 'clanking' noise.
• Tried rolling it back and forth with engine off- jams solid when pushed backwards
• Now up in the air, front wheels turn ok.

I fitted a DCCD system and an RA box a while back.

I'm thinking box or maybe centre diff- any ideas?

Tooth probably broken off one a gear, or possibly the drop gears and jamming now and then.
