Up for sale is a recently rebuilt and ready to install 742 case 8.75" third member with 4.88 Mopar ring and pinion. This center section was rebuilt for previous owner but was never installed. He sold it to me as he was told that it was a 410 gear but as I pointed out to him, the ring is clearly marked 4.89 (4.88 ), we then counted the pinion and ring teeth and I confirmed for him that in fact this was a 4.88 setup, too tall for him. I purchased to put on shelf but shelf is full so time to go.
The ring is dated April 1968 for anyone looking for such information. Without pulling it apart, I suspect this is a ten tooth pinion based upon the date and size gear ratio.
This is a clutch style Sure Grip (posi) unit with the large pinion and large universal joint pinion yoke for big block application cars, perfect for drag racing or going really fast from red light to red light or 1/8 mile.
The listing includes FREE shipping to lower 48 United States, anywhere else it will cost you extra which will be calculated prior to payment.
Please send me a PM if you interested.
