I too am interested in obtaining a rebuild kit, I want to support forum vendors in this. I am in process of trying to obtain the correct spline measurements. I do know my compressor and output houting are A/R 60 by Precision. This is first time I've pulled the turbo off this or any of my past GN's, and this is not a stock turbo so I'm not sure what the size is at this time but will by this evening (if I can translate the micrometer readings to mm.). Thanks and I'm quite pumped to tackle this project.
By the way I'm open to any "pay attention to's" while I'm opening up this wonderful toy. So far I've just opened up the compressor shroud and exposed the fresh air splines.
