Yes, you can shim the 3/4" axel spindle from behind the inner rim bearing, and the stop flange. My model 71 had shim on both spindles, and made for a noticeable amount of play in the rim sliding in and out, when I removed the shim to find out. I took the time to share what I done with my model 71 to fix much of the steering slop I had, you can take a look.

I like the wide frame front axles, as they incorporated removeable steel sleeves in the cast iron axel. Could be an idea for you if they were bad, or just find another axle.
