3020 dual wheels

9 bolt or ten bolt and what casting number on the hubs. There are several different casting used over the years.
 
I need 9 bolt . Didn?t you tell me the 4020 dual hub will work on a 3020 but the wedges are different ?
 

Info you're requesting is located in 3020 parts catalog. Note part numbers outlined in green box. Tractors listed below plus IIRC some 2 cyl tractors utilize these wedges

I believe they are same as 4010/4000 axle size which is 3/1/8.They are not the same wedges as the inside wheels.I have got correct wedges from Jim, Bowie Equiptment in Tipton Iowa 563-886-6946.He is really sharp on part numbers and knowing what works.There are actually more than one outside hub as some will take down to smaller wedges for 2520s and some will accept the larger ones . After market hubs are a lot easier to find as some of the newer 6000 series take that size.
 
Not sure about those, but axle size is the same as a 720-730. The wedges themselves might be slightly different on the two cylinders, though?? Seems I read that here somewhere that the taper is a bit different.

Yes wedges for 720/730 RC tractors has same part numbers so they will be correct.
