Asking a question; Are the rear axles on D21 / 210 / 220 the same 3.25" diameter as on a 200 ? 
 IF yes are the wedges and cast wheels interchangeable? I've a cracked rear wedge and my renter thinks he know where a D21 or 210 parts tractor may be setting.

D-21 and 200 and 190/190XT above s/n 9001 are the same 3.25" axle diameter.   210/220 are 3 5/8" and use a different two-piece clamp.

7000 tractor also uses 3.25 axles, and many came with 38's.

?????    There were many D-21 rear ends that got 210/220 ring and pinion gear sets installed (in a D-21 rear end housing) to increase the speeds 10%, but only on pulling tractors. I don't know what else you would be referring to, as a 210/220 rear end assembly would lengthen the wheelbase on a D-21 by maybe 4 to 5 inches ??

Yea, there's a few around, you can tell by the rear tire and fender curve don't match up right.

Drove down to look at tractor. It's a 200 bare back, 3 bad tires but all parts still on it.. IF new owner of this farm will sell the  tractor I plan to make offer & maybe drag it home for parts. 
 They bought the farm from an estate about 3 years ago tractor and few old implements setting in buildings. THey haven't cleaned building site yet, took out all fences and 2 large piles of trees.
