you could go with one of those conversion kits to add discs up front AND keep it SBP all the way around (still need 14 in wheels) or go with an OEN Kelsey Hays SBP 65-72 disc conversion (still need 14 in wheels. Or LBP conversion (larger wheels again) and run SBP in the back unless you convert the rear as well. Lots of choices (and money!)
