    Yes I went with a steel TO bearing made by a machine shop. They used my original one to get the right shape. I have a spare if anyone needs one. They came out very close to the original but needed slight modification on a lathe. And now the engine is going back in! I did an engine out in 2012 and now I'm doing this one in 2019. Hoping to get a few more years out of it this time. I do drive a lot so it makes sense that it took 7 years.

    Post a picture of the part please.
    It's good to see that you're getting so much use out of that car. How many miles have you put on since you bought it? It was 2010 if I recall correctly.

    Here's some pictures of the culrpit. My car has been down for many months because of this damn thing.
    I think I have put on over 25K kilometers by now. Most drives are short distance just around Hollywood. I have drove it to Santa Barbara once and to Huntington Beach a few times. For the first few years I was driving it 2-3 times a week. I have corrected some old faulty repairs to electrical, done these 2 engine outs, done suspension heim joints, and regular maintenance. I love this car a lot and I'm planning on keeping it forever. Next year I'm hoping to go to Italy to see some of the original paperwork and find out more about how the car was born.

    I've never replaced one but I have noticed that they get grooves worn in them. Not surprising that eventually it could fail. I've also wondered why Lamborghini designed the pressure plate to operate the reverse of most cars.
    I ought to make a couple of those for future stock. A pretty simple lathe project if you have a drawing or one to copy.

    I'm curious what flywheel and pressure plate were used.

    I was thinking it might be possible to use an Espada clutch/flywheel. Probably still a few of them available used. I've always wondered why they used that odd "pull" clutch setup.

    IS this the down draft valve timing? If it is how much different is the F.I specs?
