Here is an inside of my conversion to needle roller bearings(1.,2.,3.) in a 105 gearbox.
After many km run - I can say it works fantastic!

I have a gear box with lightened gears that I could install the needle bearings if I knew the dimensions to bore out the gears to and what needle bearings to install. This would resolve the issue of having to install new bronze bushings and honing them out to the correct dimensions.

Thank you for posting this,but we do need more details.We would need the +/-tolerance of the finished hole,what final surface finish of the new hole,and wouldn't it be necessary to re-harden this area? Any substantial difference in gearbox noise?
