Questions: random stuff.

[AnlaufJohn]

As the Thanksgiving Weekend approaches, I am making a list of items to fix or replace. I have some items that my local sources of Chevy information don't know or haven't had the question raised before.

First up-VIN number plate. My 66 has its VIN on the upper cab/door area. After the words 'Chevrolet,' there are two (2) "D" stamped. Looks like this:
CHEVROLET DD

What do the double d's indicate?

How much effort should be required to pull the choke cable? I've looked at the routing of it under the dash, and it looks like a lazy 'S' to the firewall. After it passes to the engine compartment, it dives down to go under the air cleaner and then up to the choke plate. The first 2/3 is easy, but to get it to engage the high idle arm, the last effort is close to 25 lbs of pull. Is that normal? Is there a good, better, best rating of lubrication products?

Last is the heater switch. I have the Thrift Air version, where the air control cable is part of the electrical 2 speed blower switch. My low speed is not working anymore, and the electrics are not available separately from the cable. The replacement cable/switch has instructions that indicate moving the flagged screw tab adjusts the cable length. Huh? Sounds like adjusting the brake cables on a bicycle. Still baffles me.

Other than that, we had our first cold night last night: 33F. Nice day to work on the Chevy.

Thank you,
