GT2052V CHRA and setting the stop screw for actuator

So guys been thinking of swapping my GT2052V CHRA as my existing one is leaking oil, moving in and out and has damaged vanes. Question is actually about how to correctly set the stop screw for the actuator on the Turbo as the CHRA may not be exactly the same as whats came out, is their a recommended brand to use thats exactly the same as whats in without going to the dealer?



Been recommended Melett and was wondering if this would be the best option? Or should I buy a second hand unit with no smoke but has a little play in the shaft? Or should I get a completed refurbished unit?



Thanks in advance Alan
