Randy,
I just took this shot for you....hopefully it helps.
I mounted them from the back side with button head fasteners. I had to drill an access hole through the intermediate plate of the latch for the lower screw. The upper one is a bit of a pistol to get to, but if you hold the release in the fully open position, you can just get in there enough to get the job done. On the inboard side I used stainless washers and nuts.
Again, hope this helps. Let me know if there is more I can offer.
