1967 Camaro Window Crank with Butternut Yellow Knobs

[STS]

I'm looking for two window cranks with #707 Yellow Knobs for my 1967 Camaro. I noticed RS3SDL2MG did a posting on 1-25-09 on window crank differences and photo included showed two such knobs in the background. Would appreciate any info on where I might find cranks like this that are for sale. Thanks.
