Ross,
I have a question. You have a 55 3100, is this the truck you are thinking of putting the Dany 60 in? You mentioned that you are changing to an IFS. This would be a 5 lug setup. Most Dana 60s are 3/4 ton truck axles. They would be 8 lug. While the Dana 60 can be converted to match your 5 lug front, it is alot of work. The other question, why do you need a Dana 60 in a 1/2 ton truck? A late 80s Camero or Firebird axle is the correct width and has the correct 5 lug pattern. My thought is if someone gave me a rebuilt Dana 60, I would sell it and buy an axle that was closer to what I needed. I sure would not spend lots of money to get something that was not remotely close and then spend lots of money making it work.
Ross, the thing to remember, this is my oppinion and it is your truck. Good luck.
Lonnie
