...it ain't much...
Howard drove four hours to try his wheels on my converted brakes (in the SNOW). Remember that moment when you first tightened the lug nuts, just before you spun the wheel? Look at Howard's expression:
He couldn't be more pleased.
Now compare your wheel contour with the one Howard and Ray used. Look at the silhouette at the bottom of the wheel, where the black rim contrasts with the snow:
When Howard put these wheels on his '60 Thunderbird, they worked with no alteration at all. I believe Ray's situation was identical. Both used 14" Ford wheels on their Squarebirds with S-10 calipers and Scarebird brackets.
I hope this helps. - Dave
