Guaranteed - unless you buy one that has already had them replaced. I've had a ton of vintage Peugeot and other Simplex equipped bikes pass through my hands. The most common problems are jockey wheels with missing teeth on the RD, and a cracked clamp/housing on the FD.
Of all the old Simplex equipped bikes I've handled, all but maybe 2 have had to have the FD replaced due to a cracked or outright broken clamp.
The good news is that Suntour replacements are cheap, easy to install, and work great.....
