I have for sale a 3.55 ring and pinion and a sure grip for an 8 1/4 axle. I don't think it's ever been used. If it has it wasn't for long. I've been hanging onto it for 5 years but I don't think I'll use it now.
One of the carrier bearings has a little surface rust from being on the garage floor when the tide came in. I recommend changing the bearing.
Asking $250+ shipping or local pickup near Virginia Beach.
