Is this classic worth converting?

If the cups are OK, great. I understand that idea. If the cups are not OK, then it isn't as simple as the $10 Shimano cartridge bb I put on my 1993 Peugeot.
I have a 1975 UO8 frame hanging in the shop, waiting for a spindle (I haven't been looking very hard, as it is way back on the project list).

It's not that difficult, guys. Here's your reasonably priced solution to this "challenge".

Then just pop on some generic crankset and roll away!

They also ship pretty fast. I ordered that exact BB Thursday and it came in today (Monday). I'd prefer something rebuildable, but I want to ride more than I want to buy a donor bike that's I'd have to shoehorn into my apartment. It screwed right in and seems nice. It doesn't work with a normal spanner style wrench though. If you buy that you will need Park Tool's BBT-22 or equivalent.

The real deal is what we've just told you - it's not a PX-10, it's a UO-8. Some people love UO-8s, some don't. $50 is a great price. Some like the way UO-8s ride just as they are. It's a very good quality bike for a late '60s/early '70s entry-level French bike, hundreds of thousands were sold back then, competing with Schwinn Varsity and several Raleigh models. Not a bad bike by any means IMO, but not anywhere near as good as a PX-10.

Becuase, alas, it often does.
The French cups in both the UO8 and PX10 are thin walled. The most common spindles you find require a thick walled cup. Unless you have some old Nervar/Stronglight spindles (and cranks) it's best to just replace the BB cups to Japanese, as it greatly widens your crank options.
I will note on my PX conversion I have thin walled Zeus cups and a Stronglight spindle; but on my UO8 conversion I have a Sugino crank and BB. You can do it either way, but the Japanese cups, spindle and cranks are just far more common. I will also note some 70s Japanese cranks and spindles play well with their French counterparts; for a list, see a period edition of Sutherland's.
