Wow, lots of great info!
Checked a bit more into this and didn't find any issues with running a factory 20-22" wheel with this conversion.
Ordered most parts today including the skid plate.
Current plate sits right up against the diff so needs more space, just as you mentioned.
Front sits right at 41" w/35x12.50-on stock 20's which are actually 34.5" and keys are cranked up a good ways at this point.
Any indication of what dealers make of this conversion when it comes time for warranty work?
