Rindelmach1 14 Report post Posted June 16, 2020 I have a 69 mach 1 with 9" rear end and 3.25 rations. Can someone give me advise on what I would need to replace the gears? cjpony has 9" gasket set for small and big bearings but I don't know which one i have.

RPM 1,190 Report post Posted June 17, 2020 12" dial/digital caliper, dial indicator with magnetic base, sockets, ratchet, 1-1/16" socket for pinion nut. You can make a spanner wrench to adjust the carrier bearings. Quote Share this post Link to post Share on other sites
