First of all thank you for taking the time to give such detailed tips. Second can you please post a link or explain what size and location to purchase the stronger diff locker hardware? Thank you brother!
It really is my pleasure. I just want to help as many as I can by sharing as much info as possible.
Here's the hardware I used for the Incision and stock spool and since switching over all my hardware on my other lockers as well, I haven't had a single issue. One of those trucks is running 4s Holmes brushless. While I was at it, I ordered 1 of each size and length of several different high strength screw packs. These came in handy when mounting the ring gear to the other different sized spools in my other crawlers. I'm always OCD about using the most appropriately sized screw for any application and having it all on hand when building is so nice. The high strength set screws for motor pinions are also a very nice thing to have on hand. I was stripping out those smaller pinion set screws all the time before switching to 12.9 grade. Now I can crank down on them and not worry about stripping them or having them come loose because of under torquing.
