Could you tell me where you got the cups? I can only find black in the right shape and size. One pair I found is only for a specific set of trucks.

I agree. The amount of yellow is consistent all the way across under the Valterra banner. This is clearly not the case on the commercial boards. If it is angled at all, it is very slight.
EDIT: That being said, you can achieve a very similar look when applying new grip tape. As seen on page one and mentioned previously by TheRealMcFly, by slightly repositioning and angling the grip tape, you can get it to look nearly identical.
I think i will just have the griptape straight across. Slanted looks odd to me even if it goes with the Valterra letters.
