Product Questions & Answers

Q:What else is needed other than this YGLF9-28 to complete the conversion of my 66 Fairlane GTA open 9" rearend? Show Less
Tim
A:BEST ANSWERHello! Other than the differential cover and fluid, it depends on the condition of the rest of your bearings and seals. It is generally a better idea to replace the seals and bearings "while you're in there", but if everything is in particularly great shape, you can reuse them. Show less
