Chevy 5 lug rear end swaps

[tonypaul]

Does anyone had a good reference on the width on chevy truck rear ends from 1969 to 2000? Or any 5x5 bolt pattern axle widths? I tried searching but didnt find any solid info. I know I can have the axles redrilled but trying to avoid that. I dont care where all the mounts are just interested in lenghts right now. I wanting to get a rearend around 56" to 58" outside to outside.
If you have a newer 5x5 lug rearend laying around from a newer truck that you can get a good outside to outside measurment for me, I would be so thankful.
Thanks in advance
