First of all your staff is very friendly and helpful, but I feel like you should get a lot more measurements from the customer before sending out parts. I ordered a Dana 60 1979 ford front axle and rotor assembly and thought this is awesome I finally got the right one after 3 attempts at Napa. Well after getting it all put together and torqued down I went to put the brake caliper back on and realized that the rotor was a 1/2 inch bigger diameter than the original and interfered with the caliper so had to take everything apart and put my old rotor on your hub. It is back together now and working fine.
