I have an '86 GT. Want to convert to 5-lug front and rear. Question I have is this; what is the most cost efective way to change the front to 5-lug? I have heard diffferent things, ie. if you change spindles you also have to change the struts, etc. Building a street/strip car, so big brake kits are not shat I want. Mostly want to get away from the 10" rotors and 4-lug. THANKS!!
