An infinite number of Gibbons each with a hammer servicing an infinite number of Revs, one or two of them would come out OK.
Just give your self loads of time, get all the tools etc ready before handm, watch the Sram videos a few times, spread everything out over your work space so you’re not knocking bits over/loosing stuff, get a few rags ready, and or yeah, give yourself loads of time, you’ll be fine.
