    If you are rebuilding the front end of the Countach and want to replace the 5109529 bush/insert, I would not use the new 5109529 that you get from the factory.
    See the pics. 3rd one shows size of the bolt OD, next the old type bush ID. As you can see there is around .0015-.002 difference.
    Pics 1 and 2 show new type and old type bush.
    The new 5109529 is around .010 larger on the ID. This would allow the suspension to change camber, toe and caster, as you drive the car.
    I do not think this is good for a car that can reach speeds in the 150 +++ range.
    ID of original bush is right at .665, ID of new bush right at .676.
    Just food for thought.

    Someone on another site asked about using a larger bolt, NO WAY. The hole in the frame to bolt fit is around .0015, a good snug fit.. You would not want any play there, as the lower control are would then be allowed to move.

    That is great info, thanks. The manufacture of said part should be notified and correct size installed in that.

    With the cost of some of the "Lamborghini" parts, you shouldn't have to use a bigger bolt or do any kind of modification.

    They might not be manufactured to original specs rather the closest in production bush is probably used as a cross over?

    That part is from Alfa Romeo rear suspension, old stock stuff can be better.

    I also used the old Alfa parts as well no major issues, a lot of the new parts seem to not fit e.g. new front hubs require new seals that Lamborghini do not supply (larger ID).
