Alright, after scouring the internet I've found some info. Some of it is conflicting.
GMT400:
10.5" FF WMS to WMS width = 67.5" (I've seen 65" as well)
GMT800:
10.5" FF WMS to WMS width = 68" (though I've seen 69")
I need to take my wheels off and measure the width of my 9.5" SF and figure out what direction to go. The 4wd guys can easily get away with this swap. For me it would require a totally different wheel setup I believe. I could probably run my stocks again and just trim the LCAs.
