1 do any of yall know what type and size of hole the disk blades on the jb/jba disk have?

2 did they come with 18" blades or 17" blades,, mine look to be 17 but there is a lot of ware on the ones that are left.

The threads/nut on end of square shaft is a 7/8 as shown below, but the actual hole in blade is square and will be larger than 7/8. By looks of pic it will be at least 1". Discs came in 16" and 18" and 18" with cutouts. Don't know if you are restoring or what but I have original op. manual and factory rear trailer hitch and full set of original disc scrapers (for 8'er but only difference is main bar length and that can be cut to any length) if interested my e-mail is open.RB
