I've had WAY more trouble with rearends than frontends. So getting that 14-bolt FF in the back is worth the swap for me. I'm getting ready to put that exact combo under my '90 Suburban. I don't plan to beat it off road, so the front 10-bolt should hold up just fine. But on the road, the 454 that's going under the hood will be torturing that rearend. /forums/images/icons/wink.gif
