I'm restoring a series 200 mounted 2-row cultivator to go on my 1948 B John Deere. I have everything except the "adapter support assembly" that mounts on the two upper front pedestal bolts. This is basically a horizontal strap with holes for the two pedestal bolts, and a big tapered "acorn nut"-type post in the middle that fits in a hole on the front cultivator bracket. This helps center the cultivator and prevents sway at the top of the cross-braces. Anybody out there have such a thing?
