Correct Air Cleaner Assembly for 1969 K10 with 350 V8 with Quadrajet?

[shiftinggears]

I have a 1969 K10 with a 350 V8 and Quadrajet carb. Carb has divorced choke. Truck has power brakes and power steering. No A/C. Truck has 4 speed manual trans if it matters.

I'm trying to find a correct air cleaner assembly. I have come across several different assemblies, but don't know which one is correct.

Does anybody have a picture of what would have been original on my truck?

Thanks in advance.
