Ok the discovery continues recieved the brackets from Covington Customs for the "CVO Street Glide" These will not wrok either.
The CVO Fender radius is 3/4 inch shorter and theses brackets raise it 3/4" so they will raise it to the stock fender height.
The Dunlop 130/70B18 rotational diameter is 25.32"
So if the rear fender hole is drilled to 3/8" and these brackets are used a 120/70/21 should be able to be installed with these.
As usual I wish to be difficult and want to use the wider (and 1.1" taller) 140/70/21 rotational diameter 29.09". Rotational diameter difference is 1.885"
The 1.885 plus the fender difference of .75 equals 2.635 total difference.
I am now seeking a bracket to allow clearance and probably will have to make one.
Will call Covington next week
(They contacted me today saying they do not offer a solution ) and maybe drive over to Bad Dad in Ft Wayne to see if they can assist.
