53030 850 Bearing - Hop Up Option

[xerocomm]

I am building a Tamiya Ford Aeromax #56309 and want to install all the option parts. I am confused, the option part list show a 53030 850 Sealed Ball Bearing Qty: 4pcs. Does anyone have any idea where these Ball Bearings install in the truck kit?

Why not get the ballbearing set for the hole truck?

If you want to install all the option for your new Aeromax?? Order all 30 bearings Not just the trany bearings.
You can find then for around $15.00

Sorry I was not clear, I already own the whole bearing set. I did not buy all Tamiya bearings, I have a complete set of Boca Bearings (Green Seal) for the truck. I figured out the 1150 Bearing locations and the 1260 Bearing locations, this was clear in the Tamiya instructions. Understood, done. The confusion lies with the 850 Bearing set that is mentioned in the Data Sheet http://www.tamiyausa.com/pdf/pl/56309.pdf under Hop-Up Options, they mention a 850 Bearing. I have looked though the Installation Manual and I can not figure out wheat these 850 Bearings are used for - any idea?
