I've made the choice that same choice a couple of times and always just went for the all-in-one board and glad I did, they are awesome and eliminate a lot of potential failure points and you know everything works. If you had a way to test your other boards to make sure they worked ok it may be a different answer, but I'd still probably go for the known.

Congrats on the pickup.

I'm pretty sure pbresource has them, finding stuff on their site is kind of a pain. http://pbresource.com/pfswitch.htm that page about 1/3 of the way down for the purple with stars, item A-14395

I'm willing to bet that if you message Pascal_J he could tell you.

manual says it should have 3 1-3/16" posts, unfortunately they never say where.

my first guess would be these 3, hard to tell from the pic for sure (from ipdb)
