I finally got my dana 300, i've been looking on craigslist for 3 month's 2 or 3 times a day.I only had to drive 6 hours round trip to get it. So now i need to decide who's adaptor to buy. I was thinking of novak adaptors or jb conversions . The jb looks like it comes with a new output shaft and i dont want to take the trans apart if i dont half to, or it's for a 2wd trans. I havent called them yet to ask because it's the weekend. what do you guy's think?
