Run either 2x2 1/4" or 2x3 3/16". Either really works. Yes you can use the stock front spring perch. What i try and do is put the drive line and the bar in the same "plane". Kind of difficult to describe. but a generic descripsion would at ride height your drive line and 2 link bar are some what parallel to each other. An exageraged example would be like in an s-10 using the stock front spring perch. The drive line is some what parallel to the ground where the 2 link bar is pointed down. You'll get a lot of pinion angle variance thru your rear end that way. On MY dually i felt the front spring perch was a little low. So i used a drop perch from bell tech that i had laying around. use 2x3 3/16. made a trip to my local trailer supply store, had some 5/8" "u" bolts made in the lenght i needed, (I always use new u-bolts) along with some new spring pads, and a new spring perchs. I then cut all the factory shock mounts, spring perchs off the axle, put an alignment pin in my new 2 link bar, mocked everything. set my pinion angle where i thought it should be and welded the new spring perch to the axle. Took everything apart, finished welding, painted and put back together. I dont have any pics. sorry.
