Now the 86 center link which is a different length, about 1-1/4" shorter than the 70 at the Pitman, Idler taper centerlines and 1/2" shorter at the tie rod tapers, cannot be used...it does have one size smaller Idler Arm Taper, but the frame Idler brackets are the same taper.

Here are my notes I posted on what I used to complete my conversion:

I was looking at parts catalog and seem to remember seeing that there was a difference with C10 vs C20 to C30? Could you findings be a little different since you have a C30?
