'46 Ford Radiator

Hi All - Nother question re: my '46 Ford - sbc combo - have installed a Billet Specialties Tru-Trac serpentine pully and accessorie system on the front of the 350 sbc engine - while it looks great it presents a problem with the location of the Radiator. Looks like I have to move it forward at least 1-11/2". Has anyone had any experiance with this and if so what problems should I look for. Seems like the sheetmetal on the front end will be affected. Many Thanks for any and all help.
