Thanks Vdog
The lincoln is wider than the C20 rear by several inches but not the C10 rear. C20's have huge drums on them which takes up axle width. So this is where I was just guessing at the correct width of the axle and b.s. needed.
Unfortunately I did not get the back spacing I wanted. Coy's has certain b.s. for certain wheels and I did not want the wide 10" rim for gas mileage reasons, but I wanted a deeper well on the wheel which would have pushed them out further w/o the need for a spacer. Coy's had recently discontinued the C55 rim that I really wanted, and had only small amount of 18's left to choose from. None were deeper than the ones I got, so I hoped that the amount of b.s. on these wheels would move them out enough, as you can see it did but not enough.

I do not think running a wider tire would have given me the width that i was looking to achieve with the spacers. Maybe next time I will try wider. but I wanted to run the exact same front and rear so that I could rotate when needed.
