Need Jockey Wheels, Simplex Prestige derailleur

I have my Dads old Peugeot UO-8 and it needs some work. The gears on the rear derailleur are missing more teeth than they have. I don't know why Simplex used plastic gears, but I guess I need to find a new set. I ordered a set of Shimano gears but I've read (after the fact) that they don't fit on a Simplex prestige. I also need a front derailleur as I don't have one at all. If anyone can help me find parts I would really appreciate it. Thanks!

Prestige derailleurs aren't too hard to find and show up on eBay commonly. The second one has a front that goes with it if you want it, too.

Velo Orange sells some pulleys that will work for you. Most pulleys are plastic. Simplex used inferior plastic. The only derailer I've ever owned that had metal pulleys was a 60's Campagnolo Record. It had steel pulleys with no teeth. I sold it for stupid money to a Japanese collector after paying ten bucks for it 20 years ago.

Older Huret Alvitt jockey pulleys were metal with BALL BEARINGS - not bushings! And since Huret and Simplex are both French, they might fit for you. Go to your local bike salvage (if you have one) and dig thru their bucket of rear deraillers for an Alvitt. Probably get the thing for $3 - cheaper than any internet pulleys.
I always keep such pulleys in a box - cause they last a long time and you can rebuild them!

Ok, I got those Shimano pulleys in the mail today. After 3.5 hours of trial and error I managed to get them to fit with some very nonstandard hardware. They worked great! I made it almost a quarter block before my chain snapped. All of the gears were solid and in line, the tension on the chain wasn't to high and I'm no power house. Pretty sure it was just the 40 year old chain. I still need a front derailleur though, Clamp on, preferably simplex. I'd like to "restore" this bike, but I'd really like to ride it. I will keep looking myself but if anyone has some spare parts lying around I would appreciate any assistance. Thanks to all!

Suntour jockey wheels are a straight up replacement for Simplex jockey wheels.
