I will be installing a 3.00 geared 9" on my '59 to replace the 4.11 it has now,it is out of a late 60's Torino with the smaller bolt pattern.... I have a full set of Wheel Vintiques steel wheels that I custom painted in the smaller bolt pattern but need to convert the front drums to match...what are my options? does anyone sell drums already converted?...do I need to buy new drums and have them re-drilled, since I probably need to replace anyway.

Thanks
JP
