I been running mine for awhile now. Got about 5k on it. No issues except the hum/vibe at 65. I swapped driveshafts with Sparky when I was up there a few weeks ago and it went away. So I have another one coming from CO. Hopefully it's not the SR pinion flange that's the problem. If it is, I bet them AZ boys probably have a few....
