Screw type clamps are correct for the A/C hoses if they have the "Tab" extension on them to indicate them on the end of the A/C as mentioned. Bill

My '63 Grand Prix has screw type worm gear hose clamps on the A/C lines.

My '64 El Camino does also.

All the A/C hoses on my '38 are crimped. You'd think they would have kept doing that into the 60's...:wink:

What a baffoon. They built 54,166 1966 Chevelles with K19 smog.

Must have also been a prototype for a generic NAPA master cylinder and a repro Delco-Morraine stamped booster too ...

And what is that on the firewall inboard of the booster ??

Good eye as usual, Jeff!.....Bill S

Appears to be a "siren" for an alarm system with hardware store wire connectors?? Maybe that's "1 of 1 prototype" also? :rolleyes2: haha!

While we are focused on that area, love the home brewed fat wire harness, tape wrapping who knows what? And what appears to be blade connectors protruding from the firewall?? :hmmm:

Didn't meet reserve....stalled at $50K,which I think the owner should consider accepting.

He should grab the cash and run....but he won't. He's convinced this is a RARE California '66 with a smog pump. He even claims GM engineers and members of Team Chevelle support this theory. I did a search on Team Chevelle for any 1966 prototype threads or posts and came up empty...:wink:
