I've got OEM ring and pinion gears from a Dana 30 & chrysler 8.25 in 3.55. I was thinking 50 for all of it. You'll need/want a brand new master install kit. But if shipped. I should be able to fit these into a flat rate box via USPS. I can cryo treat them for 100 as well. It's a 2 week wait on cryo treating though.
