Another 20-year user, here. I have the Wevo shifter, coupler and internal gate -- with a magnesium-case 915 with a clutch-type LSD attached to a 1995 3.6 liter engine. Probably 200 track events by now? I also have the later side cover and one-piece bearing retaining plate.
All I've done in that time is do regular Swepco changes, and (once) changed a failed 3rd-gear slider.
I'm going to go knock on some wood.
