Need a tailgate handle lock (SUT)

[Egan]

Guys, I'm getting rid of my swing-away spare tire mount which really exposes that the tailgate has no lock. Has anyone found a lock that works? I've seen the Pop & Lock PL1100 and it is better than nothing, but I was hoping to tie something into the other door locks. I found some automatic locks, but none of them say they work with the H2 SUT - is there a GM model that has the exact same tailgate handle?
