I’m really sorry for the trouble you’re having with this. 1. They are 6-32 screws because the bracket supplier did not have that style in metric. We will rebate you cost of the screws in the shipping. Just send an email to [email protected] 2. As for the .1” (2.54mm) jumper plugs, which is what they are called by the way, we will also rebate you the cost to get them. Amazon carries them, but pretty much any electronics or computer parts supplier will have them.
