if you want a true LOCKED rearend just weld the spiders
swapping gears / posi instal if you have never done it it can be kinda difficult because the pattern needs to be within spec and the baring preloaded other wise it will make noise and the barings will burn up prematurely if you get as limited slip /posi MAKE SHURE you get the right oil with the correct Friction modifiers to make it peform its best

I checked there already,and also at randy's ring @ pinion.I am beginning to wonder if the Dana 71 ever came with sure grip at all.Didn't want to weld it if I didn't have to,but it is looking like my only option.I'll look around a little more before breaking out the welder though.

ah ha well heres the service manual for the 70 it takes a few to load http://www2.dana.com/pdf/5312-9.pdf this should be everything you need to know on how to chance it out (and its got pictures)

The 3.07 diff is called a 71 according to the manual.They were only supposedly available with the 727.4X4 trucks with the 727 had a dana 61 in the front.I'll check with the dealer for a posi.Thanks for the info!

The dana 71 did not come up on any site that I could find.There was parts for the 61,but not under dodge trucks,and only for 3.54 to 4.10.
