I posted questions at www.texasarmor.com under 1/16 Tamiya Armor and gathered information that concluded in that Bearings instead of Bushings would be best in my application as I intend to Run it in various terrains and quite honestly be quite brutal with it as I am with my other 1/16 Tamiya Tanks..SO I ordered a set of Sealed Bearings...should be here in 7-10 business days..SO I am skipping ahead onto another section of the Sherman so I can make as much progress as possible...
Next I mounted the 2 New style Gear boxes to the lower hull..I followed the instructions and installed the spacer bolts/nuts and properly attached everything to the fwd portion of the Hull..again I used threadlock...
