360 engine vibration

ok i have the diff out now and struggling to get the sliding yoke out, so that's tonight's job. its either jammed in the transmission or the prop is too long as there is no movement to slide the prop forwards. I had to dismantle the rear UJ to get the prop clear of the diff. So still not getting closer to the the engine vibrations. But need to sort all these things out before i can go for a run in it. I'm in the stage of the more I remove the more I think the PO was on LSD when he fitted the 360. It has has top quality new bits just poorly assembled! However with the prop off the exhausts off and the car nice and high on stands i might as well take the trans out and change the flex plate. Oh did I mentions the trans sump is so distorted and over tightened and covered in red sealant that it leaks from every seam. So there's another job.
