How can I convert Accessory Attachment values to CFrames for welding? [solved]

So, I'm trying to place a hat onto a character, but since it's only being done as a local preview on the client, it doesn't automatically attach. So, I have the hat and its Attachment Forward,Pos, Right, and Up values, but I need to weld it. How can I use these values to weld it to the head of a player?

Here's what I have so far. It attaches it but it's facing the wrong direction and it's not correctly positioned, as I didn't do any CFraming.

facialHairs[customizedData.FacialHair].Parent  = DisplayCharacter;
local weld = Instance.new("ManualWeld");
weld.Part0  = facialHairs[customizedData.FacialHair].Handle;
weld.Part1  = DisplayCharacter.Head;
weld.Parent  = facialHairs[customizedData.FacialHair].Handle;
