2731 crank and flywheel

[promotor]

As above - looking for a 2731 crank and flywheel - the crank is the same stroke as Lotus T/C but has smaller counterweights. It's a lip-seal design with 6 bolts for the flywheel, the flywheel doesn't take a Lotus sized clutch but a smaller one.

UK based. Any help to locate one appreciated.

Thanks for reading.
