You CAN build a Dana for your car from a truck housing for a LOT less than what a new rear costs if you're willing to put forth the effort.
You will not go slower due to the weight of a Dana...that's been proven over and over, yet people refuse to accept it.
I have under a $1000 in a cut down Dana 60 we pulled from a truck. I had way more than that in the 8 3/4 that was all new and died within the first year.
I ran identical times (11.41) back to back weekends with both rearends.
