I know some one on here may have the answer , I've been looking every where for lager front rotors for my 88 2wd truck,I know I will have to change the caliper,I want a 4-piston set up anyway. The only ones I found is a Wilwood kit,& the one from Canada ,very nice,very expensive!. 5-Lug,correct lug ( bolt pattern) & correct center hole size?? Someone must have done this!!
