			My good friend Skip took his hose off his 68Z survivor and no, it does not have any ribs. He's the 2nd owner and a local car just like his 69Z. Car was taken off the street around 1973/4 so we have a high level of confidence its the original piece. Note the hose skin look!  Steve, thanks for other data point. That clamp change will remain a mystery.

			I'm not expert in PCV hoses but could there have been  a few different vendors that supplied Chevrolet with their own hoses? Maybe that could be why you have both a non- ribbed hose and a ribbed one? Sal

			Yes.  Most everything that was supplied to a plant had a least 2 suppliers.

			Of course agree with Darrell, but the sampling even thou small leans toward ribs not as common on say a 68 like a 69. Hopefully we can add more info as time goes on.

			I checked my unrestored 69Z. Looks to be original ribbed hose.  08C (late 69)
