After checking the parts manual I stand corrected. The NAA used a different axle support but the same pin and spacer setup as the 8N. The threaded pin wasn't introduced until the Hundred series.
Looks like you need a replacement pin (NAA-3126A) and bushing (2N-3039). The NAA used spacers like the 8N but unlike the 8N they were all the thinner (.090) 8N-3027 spacers and were placed front and rear as required - roughly three needed according to the parts catalog. The radius rods were attached to the center axle section just like the 8N and did not move when the spacing was adjusted. If the radius rods are not attached to the center axle the tractor is likely farmerized using 9N/2N parts. I'm sure Don B would know exactly what combinations might have been used.
