Hello, I joined the forum to ask about a 12 bolt rear end I recently took in on trade and I'm looking to purchase a Camaro. I figured I would see if I could find someone who needs the 12 bolt before selling it. I was told its from a Camaro, I found some information but couldn't figure out exactly what I have. Casting number 3894860NF, cast date K 1 8, stamps on housing are BT 11 13 G1 E (the E is below the other numbers)

The 12 bolt currently has new Richmond 4:33 gears, spool, and Strange c-clip eliminators. Its in great shape, been sitting in a shop for years. I don't have the stock diff

If anyone is interested in purchasing it or has any information on the codes/stamps I would appreciate it. I'm in the Seattle area

Thanks in advance

 

BT = 3.55, 11 13 = Nov 13, G1 = first shift of Detroit Axle & Gear Plant, non-posi.
Yours has been modified for drag racing, aka, spool, gear ratio, and axle retention with Strange axle bearings.
