Glen,
I like them a bit taller, considering 5" about minimum, a 12 ga with some extra LOP might deserve 5 1/4" tall. It's easy to shorten one by 1/8" but a bitch to stretch.
BTW, I've never used a skeleton buttplate and would be more interested in a solid one.
The screws that came with this one are 12x24 with .375" head .150" thick and 8x24 .220" head .120" thick, machine screw threads.
Thanks for seeking input. Keep us posted.

(It's better for installing with the upper screw on the heel to pull it both down and forward, but I'm sure more difficult to make that way.)
