There are not too many model that have that key in that colorway. 2500, 3181, 3190... none of them have 1.25 modifier, would have to mix match. You would be better off buying a new GMK full set so it's all matching and have everything you want. I am sure either myself or someone else will make a groupbuy for this at some point with smaller mods/nav set so it is more cheaper.
