Nylon timing gear? 1973 W200 318 engine

Did the factory-stock 318's come with nylon timing chain gears? I would think that I would want to replace it, if so.

I had a 1984 Chevy that had a nylon sprocket disintegrate on me on my way to work...

Looking at NAPA on this for you and I see there stock replacement is metal. as far as if it came out stock with nylon I do not know for sure. But here is the part number for I believe the stock replacement metal gear and chain kit.

Part:

NTP 103028X

Well, it's not definitive, but what was in there was all steel, no nylon.

THANKS for checking!
