Converting to Manual windows

[cyberpine]

I'm looking to convert my 87 C10 to manual windows. The power windows and locks currently down't work.

I found these for about $45 for both but says it's for a V30. Will they fit my 87 C10?

They look exactly like these which say they will fit my truck.

How tough is it to do the conversion? Should I expect to have to do any drilling, cutting or grinding?
Will parts come apart easy if there is rust?

Also, I was planning to dye the plastic door panels black (from dark blue) anyways. Any suggestion on what I can fill plastic holes with?

Thanks.
