Hi- Annoying drip of gear oil coming from the pinion seal area on my 1966 Riviera. I've searched a little on this board and see that this can either be a problem with the seal or improper torque on pinion nut/crush sleeve. Also read that getting replacement crush sleeves and pinion seals is difficult for the 9 3/8 late-60's big car diffs. One source was reported: Ratech mfg 11110 adwood drive cincinatti OH 45240 513 742 2111 Any other sources or advice? Thx!
