To re-answer Danny’s original question, it is right on the edge of exceeding rare, or maybe I should class it as exceedingly hard to find one. I bought one years ago as an NOS-in-the-box at an excellent price, only to find out is was a post-‘70 big block Chevelle cleaner (different heat tube opening on the bottom of the snorkel), at first disappointing as I needed to replace the cleaner on my Z11, then financially lucrative when I found out how few NOS ‘71-‘72 BB ZL2 cleaners were out there. I have since made my own reproductions like camaronut, and have sold several over the years. Easy to spot weld including the vacuum tube clamps on underneath, use an NOS 4 spot vent and a green A/C vacuum signal valve, and it will pass for OE, albeit a LOT less expensive.
The cleaner pictured is for L48 applications only, although in the day you could order one over the counter and put it on any engine, though most people would have used the 6485235 cleaner, available OTC for a greater length of time (6485234 was discoed first). I know because I had my best bud run the numbers on the parts locators in the ‘80’s. Interestingly, the L48 and the Z28 demanded the same 270 coil assembly, which ain’t so easy to find, either -
Regards,
Steve
