Question about chrysler rallye wheel viniques and a disc conversion

The 14 inch factory small bolt wheels are 12.25 across where the wheel center is welded to the outer band. Then it flairs out , but it may not be enough. The small bolt 15 inch steel wheels that I used to get from Coker were 13.25 at the welded area , I am pretty sure. I will have to get one out and check. That maybe enough , maybe not.
