Problem Solved
I ordered a NAG1 rebuild kit, which arrived in a week! Quality looked good, but kit was short a few parts. I emailed OPT, describing what parts were missing. They resolved this issue by shipping me the missing parts at their cost, though it took 2 weeks to do so, as they needed to source the individual parts. Overall, I'm happy the kit and OPT's service. Thank you OPT.
