Sorry if it seems i hijacked this post..Just trying to sort things out.....OK went to local junk yard they have two dana 44's in stock,One with 3.73 ration and one with 3.55 ratio....this is where i don't have any knowledge on the matter ,I retro fitted a new world T5 trany into my truck, I don't know which ratio to choose ....Anything will be better than the stock 4.10 ratio ....they want $300 for complete rear end including disc brake set-ups..... does that seem about the correct price ?????? Thanks Steve...
