No such records exist. All I can tell you are utes are much less common today than vans. 99% of post 10/75 Sandmans recorded today are XX7's. XU3's are the rarer of Sandmans in general. Palais white itself is fairly common today compared to other colours. I have 16 recorded, 3 of which are utes: 2 x XX7 and 1 x XU3.
