Guess if I could find a 12 bolt from a camero, might be something to consider. My 86 Silverado has a 4.10 rear, I have no problem at all with it less I try to go over 80. Not to many places around here to go much faster than that anyway, and I really wouldn't want to get a ticket tryin to find the top end on I-35, the police just wouldn't understand. :rolleyes: 99% for me would be between 0 and 80, I know me so I would have it over 100 occasionly or at the strip, that would be the 1%. Thats why I figured the 3.55 would be a good comprimise.
