Whether you want Currie or Dynatrac, I can help. Being an authorized dealer for both. Do you want full replacement axles or do you want to use as many of your components as possible to save $$$? To be honest, building a front D44 is not that much less than a D60 and the benefits to a D60 are numerous.
Send me a PM with what you want for a locker, R&P ratio, brakes, etc. and I will get you some pricing. You can go full Currie and get their suspension as well or go with Rock Krawler, Rubicon Express, or a whole myriad of other company's products.
A realistic budget is the determining factor here. You also don't want to build then rebuild throwing $$$ to the wind. So if cost is a factor at this point, you should think about building in stages where you won't have to get rid of products you have already installed to grow. Make sense?
Let me know if I can help.
