Ken's issue wrecked the drive chain and the engine
mounting holes, lugs and oils all scattered and its still an ongoing claim as far as I am aware, he was going to exchange the VVC, Dave Andrew's modified head (where the power was) but don't know its current position. His original doner was a BRM so would have had an LSD.
I had a VI doner and it was a std diff. I have a new PG1 with new LSD fitted ready to be fitted but it may not get there.
