Hi, I'm a newbie and just read your post. I'm restoring an 85 Haro to full factory spec. When you say restore what do you mean ? Was there any knurling to begin with ? Yours could be a rare early 85 master like mine ? For the first coupla months they were made with smooth dropouts. Check your serial number....it should say eg 048556 etc the first 2 digits are the month of production, 85 for the year .
Hope this has been some help. How's your build coming along.
kind regards Antony
