Hi there, i have a 68 gmc 2wd with 6 lug drum brakes and would like to go to disc up front but would like to stay 6 lug since i have my wheels already.. Only way i would go to 5 lug is if i could get an adapter/spacer to run my wheels.. Anyways what are my options to convert to disc and what all do i need? Any experience with certain kits? Thanks!
