Alright, so I'm sure no one remembers me, but I used to frequent DF quite a bit. Got a new Dak, '99 3.9 4wd.

I need to replace the U-joints on the rear drive shaft. I'm looking at Oreilly's and Autozone right now, (if anyones got a better place, with fairly cheap U-joints, point me in that direction too)

On the Oreilly's site, it just gives me the options for rear shaft front, rear shaft rear etc.

But on the Autozone site, it gives me a couple options with different bearing cup sizes. So, what I need from you, who have a much more extensive library of knowledge on the Dakota than me, is this: From the information provided (or any more info I could give you), can you tell me what size bearing cups I have on my truck? The options it has listed are 1.126", and 1.078".

If you don't know off hand, how would I go about finding it?

Thanks for the help.
