Still say the axle clamp plates would be first place to look. Note this kit is offered to the full range of Morgan Classics to replace leaf springs so would be able to cope with well over twice the power of your engine. It does require care in fitting and then setting up though.
It would be interesting to hear of your findings and hopefully cure so please keep us advised.
