you need to change your rim offset, put a thin spacer on or clean the calliper up with the grinder and you should clear them ok :D

prob about 8-10mm from memory and you may have to put some longer studs in to get enough bite on the nuts :D , you could try spacing the wheel off with some washers or something to work out how far you need to space the rim off the hub, if you grind the calliper its only the cooling fins that need grinding back to get enough clearance, how much clearance you need will depend on the paticluar rims your running watch out if you change rims or put a spare on the front so nothing fowls :D

My Cruiser has a 10mm spacer on each side in the front, but I can't remember what the wheel studs are off.

if its all becomes too much of a drama go find some earlier callipers with 2 big pistons and 2 small pistons the bodys are smaller and they clear fine and despite what anyone says you wont notice any difference in braking, you should be able to pick a set up for 100 bucks and you'll probably get 100 bucks for your set :D
