Decoding my truck? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I keep reading about the inside of the glove box door, so I took a peek. What's all this mean?

Model # CS20934 W/BASE 127
4G50CA HD REAR SPRING
4D29BE R V JR MIRROR R&L
4U63BB PUSH BUTTON RADIO
4F59AA FRONT STABILIZER EQ
4613AB RED VINYL TRIM
4M20CC 4 SPD TRANSMISSION
4CH2AA DELUXE AIR HEATER

Now, I know what the radio and vinyl are but what about the stabilizer? Is that a sway bar? What kind of trans is it? Were heaters an option?

BTW, this is a 1967 C20 250ci L6.

The stabilizer is a sway bar, on the front suspension. The transmission is an SM-420 4-speed, with a "granny" low gear, and floor-shifted. It had an AM radio, and the outside mirrors were known as West Coast Juniors. It had a fleetside bed (LWB) and it had heavy duty springs on the rear, whether or not the rear springs are coil or leaf. The option number (G50) is the same for either. The interior was red vinyl, as you can guess from the data plate. Heaters could be deleted, in '67, so the heater delete is the rarity. The 250 engine was the least engine you could get in a C-20, aka 3/4-ton.

Hope this answers your questions.

Can you link me to information about the motor and transmission?
