Stop in for a cup of coffee

Wrong carrier to accept my gearset. Im screwed. I would think that the vendor would know enough to verify what the gears are going into. Total waste of money.
Yep, I was wondering about that. Like Ray just mentioned, the 8 1/4" rears take certain carriers for certain ratios. I looked that up on Dr. Diff's website this morning but I didn't see anything about the 7 1/4's.
