Campagnolo power torque cup threads

I recently replaced my campagnolo veloce crank and power torque BB cups, but noticed the corrosion in the bottom bracket had severely affected the internal threads.
Do you know if there’s anything that can replace the cups without a thread but will fit a Campagnolo Veloce Power Torque crank.

    Press fit is hardly an option but although those threads look a little worse for wear, if the cups tighten*, then there is no problem.
    *and they really don't need to be very tight, a bit of Locktite would suffice as the crank centre bolt is torqued up to between 46 and 52nm. @52nm, it ain't going anywhere.

    As Pinno says, they aren't going anywhere.
    Run a tap through if necessary, clean and loctite.
    The above may be fact, or fiction, I may be serious, I may be jesting.
    I am not sure. You have no chance.

    But what I want to know is why the cups needed to be removed in the first place. They don't exactly wear out and the only reason you would remove them is an upgrade to Ultra torque (slightly different profile) or a heinous crime such as - different brand of components. Eeek.

    I remove and inspect mine annually, mostly for peace of mind. Don't want them seizing in the steel threads.

    Yes, I did this with my Pinarello (with Alu BB shell) and eventually, by virtue of the periodic inspection, threaded the cups.
    So they went in with Loctite and were never removed after that. Despite being threaded (RHS), they never moved or squeaked.
    Since then on any frame I have, I assemble with a spot of copper ease and never touch them.

    Thanks all for your comments. the crank shaft and bearings were 7 years old, so I had to replace, as they were completely warn. While I was at it I had to replace the cups, as the Poer Torque left cup comes with the bearing.
    In future I will inspect annually and not remove the cups unless the bearings are warm.
    Ideally if I do this on a regular basis, I was hoping there was a replacement for the power torque cups, with a tube fit version (not sure the correct name for those).
    Thanks.

    I’d re-tap the threads. They’re not that bad, certainly not beyond rescuing from what I can see.
