Classic & Vintage - Peugeot Bordeaux age?

I just picked up a Peugeot Bordeaux and was hoping someone could help me out with the age. The bottom bracket is stamped with Y8C3-XXXXX. It's got Dia-Compe brakes, "Shimano Light Action" rear derailleur, and "Nervar" on the cranks.

I would say that is a late 80's Peugeot with it's color banding and double water bottle mounts.
Funny it still has aFrench Nervar crank. It must be the last bit of French compnents left on the bike because they were moving into more Japanese gruppos back then . They did still use some Sachs components on some bikes too, but those were pretty much the "last gasp" components from France.
Just curious, what tubing is it made of? Is it Vitus?, Peugeot HLE? or Carbolite 103?

1988.

Chombi- How can I tell what the tubing is made of? The decals are pretty much gone so if it's not stamped on I don't think I can find out. It does have one sticker left that says "Mangalloy."

Jim- The link at the bottom of your post was perfect. I found the exact color scheme and decals on a pic of a 1988 bike. (I'm sure you saw that too) The guy I got it from (for $20) had a frame with the badge on the front from a '75-'79 picture on that website too. It had no fork though (the one on it was bent). Does anyone know how compatible a '75-'79 Peugeot would be with an aftermarket fork? I'll try to find out what model it was, I know that would be helpful. It was also a darker blue color. I bet I can get it for $10.

Edit-I'm an idiot, right below "Mangalloy" it says it huge letters "HLE"

drew your worst.
