Hey Les. I notice that these don't have threaded ends. How are the hubs retained?

I have not got that far yet any Ideas any one it good to hear how you guys are going to retain you wheels to axles

After Christmas I have to order the torque Converter

There's a reasonable deal on eBay for torque converters at the moment $77 inc free shipping. Just bought one for the Riley. -  https://www.ebay.com.auThere's a reasonable deal on eBay for torque converters at the moment $77 inc free shipping.

You can get locking collars that fit the shaft. They would probably work. I bought a couple to stop the hubs sliding inwards on the shafts.  https://www.ebay.com.au/itm/125783522045

I guess other options might be to pin the hub to the shaft or maybe do both?

On mine I was going to turn a thread on the end but have not done that yet. In fact that's about where I got up to on my build. But now I think of it I might just use locking collars as it is far easier.  More ...

yes some good deals now
