Can the front manual small bolt pattern 10" front drums and hubs on my 72 Demon be redrilled to the 4.5 " large bolt pattern ?, is it possible as ive been told it isent ??. Also can the rear axels be redrilled to 4.5 " again ive been told there isent enough material to do it the studs would be far to close the the outer edge of the axel and wouldent be safe to drive daily due to lack of strengh in the axel face .
