Not really a fan of the flat cross section wheels used on the cast but I get why it’s done. To do the wheel swap I ground off the outer rim of the stock wheels. I needed to use those hubs as they are specific to the axle/rivet post. I found some suitable Real Riders and rims, removed the spokes with a Dremel then cleaned up with a round file. Once cleaned up they were a solid press fit over the original hubs but I used a bit of glue to make sure they stay in position.
