Blazer and Trailblazer headrests interchangeable?

Does anyone know if Blazer and Trailblazer head rests are interchangeable? I really like the embroidered "RS" logo ones on the Chevy website, but it says it only fits Trailblazers. I stopped into my local dealer and they were nice enough to measure the post distances between both models and they ended up being the same, but declined to allow me to test swap a pair between their Trailblazer and my Blazer to confirm.

Just curious if anyone else has any knowledge one way or another? Thanks!
