Need parts in white

These crank windows are very old. I am trying to replace the hardware that is shown in white as all the hardware we have is in brown. I see things on your website but I'm not sure if they're the right numbers.
The parts are all Truth hardware.

The casement window keeper I think the part number is 7100. But I am not sure.

I'm curious if part number on your website 39107FK would work on these windows. Or would I have to just get the cover and the crank separately?

Thank you.
