With the Phil's videos and email support from Phil, I have had my engine out and modified and fitted the Bleazey Centa upgrade parts and bevel box mount myself. It is all back together and after a very short drive initial impressions are that the drivetrain is much smoother than previously.
Great achievement to have done it on your own ! I’m planing to do the centa upgrade after confinement but at Phil’´s place relying on his know how 😇. Targeting October, driving up to Lancaster from Normandy, and some tourism on my way back through wales landscapes.
