I don't think 33" tall 285's really fit on a key lift AWD Van without some front fender rubbing, the little front axle seems to tolerate 32" 265's. I would be more worried about the GM tie rod's than ring gear size, I carry some spares. The 1500 AWD is just a forrest road queen that really loves snow and a little mud on occasion..........
If you want 35's it will be a huge custom lift kit or straight axle conversion. I don't think there is any bolt in upgrade for the AWD IFS axle, if you want 35's done right the rest of the site crawls with big Fords for a reason.
Quigley does what you have in mind with only a few custom parts done on CAD the rest all HD GM truck, they also make them lifted now. When I talked to them a used van was OK as long as it was not in poor condition.
Just remember you did not break your dana 30 and neither did I and we both have dana 44's up front now, do we NEED to do it again or just think we do? I ran a little 7.5" 10 bolt in a G body with a 383 stroker a stall convertor and slicks for a long time but I swaped in a 9" before it broke so I hear you. If somebody made a custom bracket kit that allows a 8.25" or 9.25" IFS truck diff and shafts to bolt up to the AWD 1500 just like quigley would I buy it ? more than likely, do we need it ?????????
