I only recently have been able to get back on the WIRE,,, I didn't see this post till now, dang Mon, I have a couple 89 disc and spacers. "013" on them and no blank spot in the high rate slots.
You needed the big disc, right? PM me your address and I'll mail you one, in the ole spirit of 4x4WIRE "pay it forward".
That way you'll have a spare and keep another valuble part out of the recycle bin.
