So, update: She's back on the road w/ a temp fix. I got her put back together with the OG spacer and shims, well shim actually (total length is 113.1 mm). I've done 200+ miles, hit triple digit mph at least once, so far. No issues. I'm waiting on delivery of parts and will update once completed. Again, thank you everyone that pitched in on this. all your suggestions and help was invaluable. Cheers
