max tire size is iffy, as driver dictates that in a big way.
37 in tires are livable, though for a driver 35's are it for me.
depending on what lift brackets one has, you can potentially just drill new holes, or add a minimum amount of metel and drill new holes to run a full width ttb44.
pre 80's 2wd trucks have buckets that can be easily reworked to widen your spring width to the outside. steering isnt too bad. a few ways to tackle that as well.
viper command,
as to the 35 on 44 spindles
get some 96 bronco 4 wheel abs axles and put your 35 stuff on those, though that usually goes the other way around
if its the hat hubs you like the the 86/87 44 setup would be ideal, and just bite the cost on new wheels. junkyard f series wagons are cheap...paint em and be done with it.
the ranger brakes suck compared to the 150, and the big reason to do a ttb 44 knuckle swap is the brakes and optimum bearing setup.
OF COURSE,
"get some 4 wheel abs ttb axles and get some pre 80's buckets" are defiantly EASIER SAID THEN DONE OBJECTIVES..
but none the less....simple solutions as well.
