Your lower bearing is fine (although i replaced the lower bearing with the tapered all ***** bearing and race) For the top bearing i used a 6906-2RS i got off of ebay. I have an extra i can ship you for like 5 bucks if you need it. The bearing size is 30x47x9

Other than that i did have to mod a few minor things. The steering stops have to ground off and relocated. I Just drilled and tapped for two 10mm bolts and used those as steering stops. The stock upper bearing and race are somewhere near 14mm thick... So when i took the stock upper race out i ground it down to about 4.5mm and put it back in and put the bearing on top of it. You need the bearing to stop just just about at the bottom of the threads but not covering any of the threads at the bottom of the lower triple.

After all that it just goes right in. ... Easier said than done heh? If you have any other questions just hit me up man id be glad to help.

I did everything myself ground the spacer down with a belt sander and magnet to hold it. Then used a set of 30 dollar digital calipers i got from Lowes to measure.
