You lucked out bro! Most of the mild build threads I have read through...(Im not a mechanic but I sit at a desk all day at work so I read ALOT of threads here lol) were running D44 or Ford 8.8 in rear with the stock D30 on 35's with no problems. I honestly havent heard many people having issues with the D30 in front, the weak link was always the D35 in rear which isnt a problem for you...If you are going to lock possibly look at getting upgraded axle shafts but other than that you shouldnt have much of a problem with 35s
OR.. you could just save up your money and go ahead and step up to tons and let me get that D44!!
