"front cover off" piano recolor, please i'm desperate!

[thepianomaster]

this recolor is simple but dreadfully important to me and any one out there who likes building saloons and abandoned buildings.
i need a recolor of the sims 2 basegame upright making it's front lid, (the front of the top with the three carved panels) and "just" the front lid, invisible exposing the lovely piano insides texture thats already there from maxis. this is extremely important to me and would be greatly appreciated if done.note, i have all EPs and SPs except glamour life stuff.

 i have attached a photo of a piano, showing "in detail" what i mean by front cover off
