I received a bad part. What should I do?

Hello Mark, He should give you all your money back to you. What year box do you need ...... 2 or 4 wheel ?? I have one off a 72 or 73 2 wheel drive truck. Let me know if this will help.
Thanks for your offer but it's a 2wd box for the '79-87 model. They use the short input shaft. I sent the seller these photos several days ago so he's known what it looks like. I have since wiped off the gear on the worm shaft and it's just as bad if not worse than the one on the pitman shaft.
Thanks, Mark
