At what point to go Dana 60 ??????

If I started with nothing I would have built a 60. I had the 8 3/4 already in the car, so it was worth it to me to keep it.

When I got my 68 340S basket case , w/ no baskets , the first thing I did was take the 8 3/4 , 3:90 limited or whatever slip out and put a dana 60 in it . At my age I don`t need any surprises from a rear end and then later trans. explosion. Been there done that.
