wondering if anyone else had this problem

[werked 66]

when i first purchased my mustang i had drum brakes all around. then i installed front power disc brakes . when i finished the job everything look fine but when i went to put the car down on all fours i noticed that the front wheels would not spin when i tried to spin them so i put the car back on jack stands i looked very careful at every detail until i noticed that the style of stock rims in the front were diffrent than the ones in the back so i swaped them front to back and back to front that took care of the problem now the wheel spins fine does anyone know if there where diffrent style rims for disc and drum also i was thinking of putting 16 x 7 american racing torq-thrust II on my car does anyone think that the problem i had with the stock rims my give me the same problem with these rims i realy appreciate any help on this subject also does anyone think i can go bigger without having to mod the wheel openings


thanks for the help
