Chris,
You need some wiggle room in the R/O to shim the windows, to make sure they are hung plumb/level/square. That is why spec is typically 1/2" larger all around.

A lumber yard/supplier can get vinyl replacements made to order, but they will be more expensive.

As it's a sunroom, you can step down a size, trim the inside, and use Azek trim around the outside. Or sawzall/shave the studs as needed. We do either/both.......
