I had a look at a ktram chassis the other day and noted that the crafty buggers have used an almost exact copy of my diff mounting scheme. I'd sue 'em but they copied it before I did mine, the swine.
Gives me some confidence that it's a good idea that will work. Uses suspension bushes to put some rubber between the cogs and my backside. Photo

You must have copied our design then








NOT!

They might have looked at our design too... they must have a lot of people sneaking around looking for ideas!
