I've got an 03 Cobra IRS center section for sale. It has about 45k miles one it. It has 4.10 gears in it that were installed 5k miles ago. It has the V6/GT pinion flange on it since it was in my V6, but I'll put the cobra flange on if the buyer would like. It's in great shape and has no problems. $400 plus shipping and paypal fees.
