1. for older bushy with the 2 LPR holes:
Take a dremmel and connect the 2 holes into 1 line. Now u can use a quarter or a flathead screwdriver - that's what i did
2. If u have a blind bolt and the ball detent tension is too soft:
Cut about 1/8 " of a ball pen spring and just add it up to the original spring. It'll make the bolt to hold the bolt pin tighter.
3. i did the bright red LED.
4. 25 mg microswitch.
also not in pic is FS feedneck and FS ASA.
