Thanks. I found the adapters on crawford. I think I got all the parts and pieces lined out. He really wanted the smt10 digger but they are hard to find for a decent price so probably going to settle on the ground pounder. There's not many options out there for a good solid axle mt that's RTR. I have an old wheely king, thought about trying to find an unopened one of those but decided to get him something new that's still in production. It'll be good enough for a while until he decides what direction he wants to go.
