Help with Original Ultima

[nick f]

I'm trying to restore an original Ultima and I would like to get some new modern aftermarket rims and tires. Something around 2.2 inches for the fromt and rear. Now the rear is not a problem because the hex is the common size for most tamiya and proline rims but the front. I'm lost. It's a 4mm shaft where most other are 5mm and I cant seem to find a 4x10mm bearing. Do I need to change the fromt axelesto something more common?

Thanks

Just a photo for example....maybe you can take a front axle to your local hobby shop and find something close? I'm sure you can get something in the ballpark that you can shim to fit the newer buggy rims.....
