1969 Z28 OEM Smog Tubes

[toylman]

I learned that these tubes are Not correct for a 1969. They were used in 1973 and probably a few other years. If anyone knows the years of application, I'd appreciate knowing. Thanks
The ink stamped 29295 was used in 1969.
I am very familar with C3 LT1s and even though I admire the 1st and 2nd gen Z28s I have limited knowledge regarding them. I believe the tubes in the first pictures are correct for a 69 Z and the tubes in the group picture are for 67-68. The first pictures are very nice survivors and the group ones are restored. I also have a NOS 29295 diverter valve for a 69; with the stamp vs the sticker which started with the 1970. Email me at [email protected] if you have an interest.
