I am doing the Team Durango gear diff conversions for the Team Associated B44 again.
A slight change on how they were done before. They now have a slot in the back of the gear and a groove on the shaft for an E-clip. They use a 2mm pin which is slightly larger than the kit pin. This is mainly for strength.
The cost is £20 for each shaft if you supply the Team associated input shaft and the Team Durango gear.
Thanks Ben
