After a couple friends looked at the rear end it does have scars on the ring gear but they are richmand after market gears so the rear enf has been upgraded, even though it still is a 10 bolt, I dont have alot of money to fix or upgrade because of what the engine is costing me, So I am going to run it until it goes, but I noticed that there is a re-in forced cover for sale with bolts that touch the main caps with only about 10 pounds of tourque on them for 150 bucks, If I was to get one of these covers would it help or would I be wasting my money, hopefully the rear end will make it this season and next winter I can save some money and I want to back Half the car with ford 9 and make a big tire car. :?
